D.Electron Z32 CNC Alarms

D.Electron Z32 Numerical Controller Alarms complete listing for Z32 CNC machinists programmers setters.

SERIOUS SYSTEM ERRORS

Should the Z32’s OS detect a malfunction, it will activate a system error condition and halt the NC.
This situation may be recognized by the following being displayed on the command line:
** errorgen xxxxxxxx
where xxxxxxxx is an 8-digit hex code describing the error.
All errorgens may derive from software errors (since a programming bug may do anything) but also indicate specific hardware faults or application software problems.
Should the errorgen’s reasons be unclear, the user should carefully note it down (paying attention to the zeroes’ number, which may completely change the code’s meaning) and notify D.Electron.
Any errorgen’s different from what reported below indicate malfunctions which should be notified to D.Electron.
In case of serious system error, any NC’s capability is disabled; the keyboard will not work; and only safe null sequences (zeroes) are issued through the link.

errorgen 00000100

The PC could not run some mandatory program before the next machine cycle.
This may mean that the PC’s processor is too slow and can not service all mandatory functions.
It may also mean that a fast non–programmable logic section (MODULE 2, MODULE 4 or MODULE 8) is too long. In this case (unless it is due to an endless loop error) try recompiling the logic with -o optimization option, and install a faster processor.

errorgen 00000110

The errorgen 00000110 for fast interrupt cycles is an alarm designed to signal anomalous situations that are currently being experimented, and normally it never appears. Should this message appear, please notify D.Electron.

errorgen 00000120

The errorgen 00000120 appears when there is an excessive delay in reading or writing operations to the RAM of the PC.

errorgen 00000800

The ML programmable logic installed by the user has an excessive average duration.
Reduce the logic size or compile using the -o optimization option, or install a faster processor.

errorgen 00001000

The ML programmable logic installed by the user lasts more than a 24 ms. cycle.
If there are no endless loop errors, reduce the logic size or compile using the -o optimization option, or install a faster processor.

errorgen 00001110

Exclusively for FlorenZ-Linux systems, 2 mS interrupt overlap.
It is originated by a too slow processor or (most likely) by an inadequate video driver.

errorgen 00001200

This alarm may come when a simulation of the Z32 is done under Windows or FlorenZ, if endless software loops are executed, that might bloc the computer.
For example, a PLC error generating an endelss software loop originates an errorgen 0000100 on a real machine but might completely bloc the computer during a simulation.
These situations are detected and originate the errorgen 00001200, allowing the operator to correct his programs.

errorgen 00004000

Generic unimplemented instruction error.
It may be caused by an hardware error, causing the PC to misread the memory and consequently attempt to execute garbage instructions.

errorgen 00004400

Possible only in Windows or FlorenZ systems.
The RAM memory reserved for the Z32 real-time elaboration is too small.
Please, install an updated version of the “Z32 Driver” software.
Attention: together with the “Z32 driver” software it is recommended to update also the “Z32 for Windows” software.

errorgen 00004F00

OS checksum error.
It indicates that the system RAM is corrupt, and therefore in all likelihood an hardware fault.
It could also mean that somehow some program succeeded in overriding the built-in safeguards and overwrote the OS reserved memory area.

errorgen 00004FF0

ML logic program checksum error.
The same diagnosis applies as to errorgen 00004F00.

errorgen 00005000 – 00005FF0

Alarms generated by the PLC, to manage special forbidden situations. For further information, refer to the machine-tool manufacturer.

errorgen 00008000

Alarm message caused by illegal software installation. The master link board installed has not been enabled or the enabling code is wrong.

errorgen 00008001

With Z32 installed under NT, this alarm message is triggered when a DES107 master link board is entered as a software environment setting. This board cannot be supported in NT environment. The alarm appears on the event display after the invalid license number warning.

errorgen 0000C000

It is the sum of two alarms: errorgen 00004000 (illegal instruction) plus errorgen 00008000 (illegal installation).

errorgen 0000C400

It is the sum of two alarms: errorgen 00004400 (RAM memory too small) plus errorgen 00008000 (illegal installation).

errorgen 00010000

Indicates a software malfunction that should be notified to D.Electron.

errorgen 00020000

Indicates a software malfunction that should be notified to D.Electron.

errorgen 00040000

Indicates a software malfunction that should be notified to D.Electron.

errorgen 00080000

Generated when a Z32 software version with serial emulator is installed, without the
appropriate key or with a key not enabled.

errorgen 03000000

Indicates a software malfunction that should be notified to D.Electron.

errorgen 05000000

Indicates a software malfunction that should be notified to D.Electron.

NUMERICAL CONTROLLER ALARMS

NC’s alarms are displayed in code in the display video area dedicated to that purpose.
The alarm code is displayed over 4 hexadecimal digits (0-1-…F).
The last two digits indicate the generic alarm’s category, while the first two specify it in detail.
In general, the lower the category, the more important the alarm; lower categories’ alarms are those displayed should more than one alarm be active at the same time.

CN..02 – Initialization alarms

At every power up, the Z32 performs a series of checks on the internal PC’s circuitry as well as on the DOS operating system structure: should an anomaly be detected, the alarm CN..02 will be displayed.
In such a case, the operator will have to note the alarm code and notify it to the support service.
The following alarms have been programmed:

CN0102 – CMOS DISABLED

Appears in the case of serious system error errorgen.

CN0202

Malfunction in the NC disk file save routine. This indicates a serious hardware or DOS operating system malfunction. Turn the computer off and then on again. Upon restart, a message will be displayed stating that numerical controller’s files may be corrupt and special care should be taken to ensure their integrity. If file 127, upon restart, contains an “x” instead of the “T” for the tool on spindle, the “x” can be simply deleted in order to restart the work. It is recommended to check all the tools in the tools’ table.

CN0302 – ANOMALOUS LINK POSITION SETUP

Indicates that axes’ setups defined in TARAT regarding detector or reference positions in the link are incorrect. It is not allowed for a detector or reference channel to be connected to more than one axis, not even if belonging to a different process.

CN0402 – ROTATIVE AXIS INCH SETUP INCORRECT

Indicates that the inch rotative axis detector step is above 0.005 degrees. This alarm may be only generated upon power up.

CN0502 – ANOMALOUS Z-LINK DATA STRUCTURE

Incorrect setup in the Z-Link data structure.

CN0602 – ANOMALOUS FILTER SETUP

Indicates that the axis setup as defined in TARAT for reference output filters are incorrect.
This alarm is triggered on start-up if the same filter is associated to two different axes (also in different processes), or if filters are required with an origin number exceeding 16.

CN0702 – NODES CONNECTED TO Z-LINK INFERIOR TO THE SETUP

In the peripheral fiber optic system (DE1065 and DE 1075 master-link boards) the number of connected nodes is defined in the setup. If the number of physical nodes is inferior to calibration, a CN0702 alarm will be triggered.

CN0902 – ANOMALOUS AUXILIARY SPINDLE SETUP

Alarm caused by an error in the management of double spindle and table spindles under G133KA0 – KA5. The setup of the auxiliary spindle, defined as a continuous axis with logical number 12, or the setup of the table spindles should be entered in compliance with specifications, otherwise the CN0902 alarm is triggered on start-up.

CN0A02 – CYCLE/REV FORCING FOR Z-SER SPINDLE

This alarm appears when an unpowered spindle detector 2 has been defined in the machine settings, and the spindle detector is via Z-ser.

CN0B02 – INSUFFICIENT RAM SPACE

This alarm is released on installing Z32 under DOS if the available RAM space is not enough to support the Z32 programs (less than 16 MB).

CN0C02 – Z-SER OR Z-STAR: WRONG MASTER LINK

This alarm appears when Z-SER or Z-STAR settings are defined, but the master-link type is not right. For example, the master-link DE1075/1 is defined, the Z-SER section is empty and Z-SER transducers (or references) are defined.

CN0D02 – WRONG Z-STAR SETTINGS

This alarm appears when the Z-STAR drives settings are not consistent.

CN0E02 – WRONG SETTING: ZERO SEARCH TYPE ENDAT FOR NON ENDAT AXIS

This alarm appears when an Endat-type zero search is defined in the settings, but the relative axis board (can be only a Z-STAR axis) is not Endat.

CN1002 – WRONG CONCENTRIC AXES SETTINGS

This alarm refers to the concentric axes functionality. This alarm appears in the start-up phase when the concentric axes settings are not consistent with specifications.

CN1102 – PRM[ ] INITIALIZATION FAILED

This alarm refers to the PRM[ ] (permanent parameters) functionality. This alarm appears in the start-up phase for the following reasons:
– Requested PRM[ ] functionality activation with master link DES107 (that doesn’t support the PRM[ ] parameters)
– It is not possible to create the CMOS file used for saving the PRM[ ] parameters

CN1202 – BAD SETTINGS OF CYLINDRICAL AXIS

This alarm refers to the machine settings activating the “cylindrical axis” functionality (G149). This alarm appears in the start-up phase if any of the settings related to the cylindrical axis is missing or not conform to the specifications.

CN1302 – ABSOLUTE AXIS, AXIS TRAVEL TOO BIG WITH RESPECT TO THE ABSOLUTE TRAVEL

This alarm refers to absolute axes with end-of-travel (linear or rotary. It appears in the start-up phase if the axis travel (comprised between the positive and negative end-oftravel) is too big with respect to the absolute travel. Numerically: this alarm appears if: (axis travel) > (0,8 x absolute travel).

CN1402 – ABSOLUTE AXIS, FRACTIONARY GEAR-RATIO, NOT SPECIALLY-ENABLED

This alarm refers to absolute axes, cyclic, without end-of-travel. It appears in the start-up phase if the absolute travel of the transducer contains a fractionary (non integer) number of axis turns. This alarm may be eliminated through a supplementary setting.

CN1502 – ABSOLUTE AXIS, FRACTIONARY, ABSOLUTE TRAVEL TOO SHORT (< 10 AXIS TURNS)

This alarm refers to absolute axes, cyclic, without end-of-travel, having a mechanical gearratio such that in an absolute travel of the transducer are contained a non-integer number of axis turns. It appears in the start-up phase if the the axis turns contained in an absolute travel of the transducer is less than 10. The reason of this alarm is that in these conditions (fractionary ratio between absolute travel and an axis turn) the absolute travel must contain many axis turns (at least 10) to allow sufficient safety margins and safety zones to be sure that the axis movements may not lead to positions where the axis transducer gives an uncertain output.

CN1602 – ABSOLUTE AXIS, FRACTIONARY, TOO SMALL DISCRETIZATION

This alarm refers to absolute axes, cyclic, without end-of-travel, having a mechanical gearratio such that in an absolute travel of the transducer are contained a non-integer number of axis turns. It appears in the start-up phase if the number of “pulses” generated by an absolute travel of the transducer is higher than the maximum allowed by the internal formats of the CNC. Remember that in one absolute travel no more than 231 pulses may be contained. If this alarm comes, please check the “pulses per turn” item in the Z-Star settings.

CN1702 – ELIMINATE THE ALARM OF THE OTHER PROCESS, THEN REBOOT

This alarm comes at the start-up, if the initializing procedure is aborted in a critical phase, due to an arror CNxx14 detected in a different process. In this case:
– on the original process the original alarm CNxx14 remains. This alarm remains also if the error is amended because if the initializing procedure is aborted in a critical phase it is no more possible to restore the normal operation: it is necesssary to turn OFF and ON.
– on any different process, the alarm CN1702 comes: “ELIMINATE THE ALARM OF THE OTHER PROCESS, THEN REBOOT”

CN1802 – WRONG SETTINGS FOR SUBPROGRAM-AXIS

It comes at start-up if settings of one or more subprogram-axes are wrong.
Good settings should be:
– logical number not > 12
– associated subprogram in the range 1-98 or 128-230
– settings: rotary axis, without position transducer, without reference output, without zero, without repositioning

CN1902 – WRONG ADVANCED MANAGEMENT FOR ABSOLUTE TRANSDUCERS

It comes at start-up if the advanced management for absolute transducer is requested for an axis, but its transducer:
– is not an absolute multiturn EDat or Biss
– is cyclic and the number of pulses transmitted by the ZStar dirve is not power of two

CN1A02 – SYSTEM FILE NOT PRESENT IN ARCHIVE-PROCESS

Related to multiple-head machines. It comes at start-up if in one or more archive-process the system files are missing (origins table, tool table, base origins table).

CN1B02 – NO Z-LINK PERIPHERAL DEFINED IN MACHINE SETTINGS

It comes, only in FlorenZ systems, if not any peripheral Z-Link has been defined in the machine settings. It may be eliminated with a special setting in the file INI (address 28A30B = 1).

CNC002 – PROCESS 1 SOFTWARE OPTION

Alarm related to the software options. It appears when activating the Process 1 without having installed the correct license that enables it.

CNC102 – PROCESS 2 TO 5 SOFTWARE OPTION

Alarm related to the software options. It appears when activating the Process 2 to 5 without having installed the correct license that enables them.

CNC202 – GANTRY AXES SOFTWARE OPTION

Alarm related to the software options. It appears when activating the Gantry Axes function without having installed the correct license that enables them.

CNC302 – POLAR/SCARA AXES SOFTWARE OPTION

Alarm related to the software options. It appears when activating the Polar/Scara Axes functions without having installed the correct license that enables them.

CNC402 – TCP/IP ETHERNET SOFTWARE OPTION

Alarm related to the software options. It appears when activating a TCP/IP ethernet connection without having installed the correct license that enables it. This alarm is only triggered when a TCP/IP ethernet connection is established with an unauthorised Z32.
However, this alarm does not impede the ethernet connection, so as to allow the embedded system (which only operates in a networked environment) to receive the authorisation file and therefore, to establish the authorised ethernet connection on restarting.

CNC502 – TOO MANY AXES

It comes at start-up if in the machine settings more continuous axes are defined than supproted by the CNC hardware.

CNEC02

Similar to CN0202. Indicates a permanent memory temporary data area fault detected at startup. It may be caused from an incorrect CNC CMOS memory initialization, or from a serious hardware problem.

CNFF02 – MASTER LINK OBSOLETE, NO MORE SUPPORTED

This alarm comes if the Z32 is equipped with an obsolete ISA-bus type master-link: DES107, DE1039, DE1065.
Due to the fact that the processing power available for these types of master-link is too low, starting from the software release Z32 T112-1 these master-link boards are no more supported.
The last software version supporting these master-link boards is the T111-4 (but not all the features will be present; depending on the processor type).

DO NOT SHUT-OFF THE MACHINE, WAIT UNTIL THIS ALARM CHANGES IN CN2A07 OR WAIT AT LEAST FOR 2 MINUTES
This alarm comes when an updating of the firmware of the digital drives SP-Evo is in progress. It may come at the start-up phase after a replacement of a power drive module or after an updating of the Z32 CNC software, because at the CNC start-up the firmware of the drives is checked and, if necessary, updated automatically.
This alarm is replaced by the alarm CN2A07 when the updating is completed.
The time duration of the updating is normally terminated in less than 2 minutes. After this time, please restart and try again, and if this alarm doesn’t disappairs, call D.Electron

CN2A07 – UPDATING OF THE DRIVE FIRMWARE COMPLETED, PLEASE RESTART

This alarm comes when an updating of the firmware of the digital drives SP-Evo is correctly finished. It may come at the start-up phase after a replacement of a power drive module or after an updating of the Z32 CNC software, because at the CNC start-up the firmware of the drives is checked and, if necessary, updated automatically.
Please restart the system to activate the new firmware.

CN..08 – Z-Star Alarms

These alarms appear when errors are detected in the connection (optical-fibre link) between the master-link and the Z-Box.
The first two characters of the alarm code contain the map (8 bit map, where 8 is the maximum number of connectable Z-Box’s) of the Z-Box’s that are not communicating in the right way with the master-link.
For example, is there are two Z-Box’s, the following errors can appear:

CN0108 – ZSTAR: CONNECTION ERROR TO ZBOX NR. 1

This alarm appears when the first Z-Box is not communicating in the right way with the master-link.

CN0208 – ZSTAR: CONNECTION ERROR TO ZBOX NR. 2

This alarm appears when the second Z-Box is not communicating in the right way with the master-link.

CN0308 – ZSTAR: CONNECTION ERROR TO ZBOX NR. 1,2

This alarm appears when the first and the second Z-Box’s are not communicating in the right way with the master-link.

The connection error can be caused by hardware problems, like not connected or defective optical-fibre, failures in the peripheral boards contained in the Z-Box, etc.
Further details can be found in the PLC variable HHTIMES (see the Programmable logic manual).

An alarm not related to a Z-Box is also possible:

CN0008 – Z-STAR: SLOW RESPONSE TO REAL-TIME SYSTEM

This alarm appears when the real-time PC shows a slow response to the very stringent real-time requirements of the Z-Star system.
It may be due to PC mother-board, BIOS settings or software drivers not compatible with Z-Star.
To help to eliminate the error, please communicate to D.Electron the value of the PLC variable HHTIMES[8]. It contains some further detail useful to D.Electron.

CN..09 – Link alarms

The OS detected a problem in the peripheral connection link; this may be either hardware or software generated.

CN0009

Link closing with incorrect fiber optics. It is an unstable alarm condition associated to sporadic alarms. This message appears in the case a fiber optic link to peripherals has not been closed correctly, i.e. when the fiber optic end has not been cut perfectly on some node, or when there are strong optic losses, e.g. as a result of fiber crushing or too small bending radiuses.

CN0109

Indicates a malfunction in the peripheral connection link. It may be caused by electric interference or a hardware fault in the connections, the PC or some of the peripherals.
Resetting the PC this error should disappear. If it happens only very rarely, it could be tolerated (to give an idea, once a month should not be tolerated).

CN0209

Link starts with control register unwritten (slow processor).

CN0309

The same as CN0209.

CN0409

Parity error

CN0809

Frame error (bit longer than it should)

The following codes may be compounded: CN0209 – CN0409 – CN0809 – CN1009:
CN0609 02 + 04
CN0A09 02 + 08
CN0C09 04 + 08
CN0E09 02 + 04 + 08
CN1409 04 + 10
CN1C09 04 + 08 + 10
etc.

The alarms type CNxx10 refer to the permanent CMOS memory errors.
They may be classified in two sub-types:
– Alarms type CN0x10 (the first character following “CN” is the number zero)
– Alarms type CNyx10 (the first character “y” following “CN” is different from zero)

Alarms type CN0x10
They are generated by four basic types of alarm: CN0110, CN0210, CN0410, CN0810 (see below).
Due to the fact that one or more of these basic alarms may be present at the same time, an error CN0x10 will result, where “x” is an hexadecimal number (0, 1, 2 ,…, 8, 9, A, B, C, D, E, F) generated by the sum of the four basic alarms 1, 2, 4, 8.
Examples:
CN0F10 is generated by the simultaneous presence of all the alarms,
CN0710 is generated by the alarms CN0110, CN0210 e CN0410…
Normally the simultaneous presence of more than 1 alarm of the type CN0x10 is originated by battery problems (the battery is used for the CMOS memory backup in the master.link board), or by a missed CMOS initialization.
As the alarms CN0x10 represent CMOS memory errors, they permanently last, even if the CNC is turned OFF and ON.
To eliminate these alarm, the most efficient mode is to reinitialize the CMOS memory.
But this operation will destroy all of the data memorized in the CMOS memory. If this is not wanted, the operator may correct manually the CMOS errors and subsequently eliminate the alarms CN0x10 with the following procedure:
– launch the internal CMOS files editor (activity 5)
– write the string “CNXX10 OFF”
– press Enter
– press RESET
Example:
5 NUMCAT: CNXX10 OFF
Warning: the string must be exactly as shown:
– one (and only one) blank to separate the fields
– no any additional blanks nor at the beginning, nor at the end

CN0110 – Service CMOS memory error

Indicates that upon power up, the service CMOS (which contains the ML logic’s permanent data, dynamic axes setups and other data) has become corrupted and therefore
unreliable.

CN0210 – Error: Sequence files Z32

Indicates concatenation errors in the Z32 files. As result of this error entire sections of one or more Z32 files can be lost.

CN0410 – Z32 file checksum error

Indicates that one or more Z32 files had a checksum error upon powering on. The area subjected to checksum error will be replaced by diesis marks ####…

CN0810 – Error: parameters PRM[ ]

It is shown in the start-up phase for indicating errors in the PRM[ ] parameters saved in the permanent memory.

Alarms tyep CNyx10 (where “y” is different from 0)
They are alarms showing errors in the CMOS memory management.
They may not be eliminated through the editor procedure “CNXX10 OFF”.

CN1010

Z32 files are corrupted; this indicates an inconsistency in the Z32 files memory.
To restart it is necessary to turn the NC off and on again. This may have to be done twice to get rid of the alarm.
Should this alarm be triggered, carefully check file integrity before restarting and always notify D.Electron.

CN..12 – Axis detector alarms

The Z32’s transducer system is equipped with self-check circuits capable of detecting:
– power faults or detector output signal anomalies;
– step loss due to excessive speed.
– abnormal position coming from an absolute multi-turn rotary transducer
In these cases the processor is notified that the transducer’s data are no longer reliable and therefore does not allow axis movement. The Z32 subsequently triggers the CN..12 alarm.
The first alarm code’s character details the memorized anomaly type:
1 = overspeed
2 = power
3 = both power loss and overspeed
4 = absolute multiturn rotary encoder with abnormal input position
The second alarm code character (x) indicates the logical number of the axis for which the alarm has been generated.
To eliminate the alarms 1-3 the operator must execute the activity 7 (ZERO).
To eliminate the alarm 4 (normally coming only when installing the machine) the installer may:
– extract the encoder and rotate it to a normal position
– or, better, activate the advanced management of absolute multiturn transducer of this axis
Should more than one axis be in alarm mode, the code displayed is the one referring to the axis with lowest logical number, and switches to the next available code when activity 7 (zero restart) is executed.
Any CN..12 alarm is immediately displayed upon power on, even if the alarms are referred to axes either set up as “not live”, or indexed ones.
Examples:

CN1x12

Indicates an overspeed alarm (likely causes: electrical interference, false contacts or glitches, excessive vibration or speed).

CN2x12

Indicates a transducer alarm connected with its power source (likely causes: battery has gone flat, electrical interference, false contacts or glitches).

CN3x12

Indicates a transducer alarm for both power source and measured speed (likely causes:
very strong electrical interference, false contacts or glitches, battery gone flat or malfunctioning).

CN4x12

Indicates that the multiturn absolute transducer (EnDat or Biss) outputs an abnormal position. To eliminate it:
– extract the transducer and rotate it to a normal position
– or better, change the settings to activate the advanced management of this transducer

CN..13 – Axis movement alarms

They are alarms connected with the axis movements’ handling and other events detected in real-time, independently from the part–program flow. The Z32 continuously monitors the axis quotas, as specified by the machine setup, both with machine standing by and operating.
If the axes do not follow the desired quota closely enough (as defined in the system setup) the NC triggers alarm CN..13.
CN..13 is also triggered in conjunction with other axis movement – related alarms and other events.
In particular:

CN0013

Excessive error during a movement. This may be due to:
1) incorrect circular profile traits programming where a segment’s beginning does not coincide with the previous’ ending.
2) one or more machine axis did not follow NC’s commands with enough precision.
This may depend from a speed variator fault, or from mechanical hard points during the axis run, or from excessive work speeds. Verify the programming before everything else, and anyway, before contacting the technical support, display pursuit errors to know which axis caused the error (see chapter “Operating Modes”, paragraph “Special Displays: Axes and Axis errors”).
The trigger threshold for this error depends from the corresponding setup parameter (normally a few millimeters).
This error is forced by the NC’s OS in various occasions, e.g. during some external program’s execution: programmable logic installation forces a CN0013 error.

CN0113

Excessive error during positioning. This indicates an error which took place during the final positioning phase, or on an axis that should have been kept still. It appears normally if the machine axes are moved through manual keyboard controls without NC’s intervention. To locate which axis triggered the error, pursuit errors must be displayed (see chapter “Operating Modes”, paragraph “Special Displays: Axes and Axis errors”).

CN0313

The processor sent to the axis motion controller an incorrect command. This is an internal alarm which should NEVER trigger.

CN0413

During a blocking/unblocking procedure, the logic kept FEED HOLD longer than five seconds. Consult the machine tool’s manufacturer.

CN0513

Relative to a measure movement in G61. After making contact, the feeler retracted to movement beginning without contact interrupting, or, the contact was already established before the feeler started moving. It may depend from a programming error (a measure movement has been programmed without detaching the feeler) or from a hardware fault (the feeler always reports contact). See also the programming manual.

CN0613

Relative to a measuring movement en G61. It comes if, after the first touch and its release, during the second search the axis, instead of going forward toward the piece, goes back past the point where the movement begun. It is a very rare alarm, due to uncertain measuring probes with multiple commutating fronts. If it comes frequently, inform D.Electron.

CN0713

G63 overshoot. During G63 tapping or G33 threading, this alarm is triggered if the axis overshoots the endpoint of more than the set up quantity, because the chuck inversion is not fast enough or because the tapping movement is inverted due to an incorrect rotate direction recognition when the movement started.

CN0813

Copying buffer is full. While copying, the Z32 uses an accumulation buffer where data are stored before being transmitted to the PC; this alarm indicates that the buffer is full because the PC (external, connected through a serial port, or the Z32 itself) is not reading data fast enough or at all.

CN0913

Analog feeler deflection out of range. Indicates that the analog feeler’s deflection is excessive, beyond programmed emergency deflection if it happens during a G111S movement, or beyond setup emergency deflection in the other cases (manual feeler movement). This alarm appears also when height control is active (G146), if during a movement the sensor distance from the surface is smaller than the sensor negative tolerance.

CN0A13

Emergency quotas exceeded during copy (G111).
This alarm appears also when height control is active (G146), if the maximum deviation from the programmed surface (symmetrical in positive and negative way) is exceeded.

CN0B13

Feeler lost contact from model during copy (G111). This alarm appears also when height control is active (G146), if during a movement the sensor distance from the surface is greater than the sensor positive tolerance.

CN0C13

During a G111S copy init, the movement ended without model contact ever being made.

CN1013

“Live” axis anomaly in a SCARA manipulator: both axis couples, physical and linear virtual, are alive (e.g. if the couples VW and XY are both defined live, or both XY axes are not defined live).

CN1113

Negative W axis in a SCARA manipulator. A SCARA manipulator’s peripheral axis assumes a negative value during movement.

CN1213 and CN1313

Alarms relative to errors in DNC transmission from a host using codos type 16 commands (e.g. ZTERM).
The Z32’s OS monitors some pointers to the DOS files provided by the host, and triggers an alarm if these behave abnormally.
In particular:
– if the number of characters transmitted by the host (displayed in command Ris 6) does not equal the number of characters received by the Z32, a CN1213 alarm is triggered.
– if the host’s DOS file pointer (displayed in command Ris 5) is incremented by more than 1450 characters, an alarm CN1313 is generated.
Keep in mind that CN1313 alarm may be issued if the file to be transmitted contains a large number of empty lines. Reason:
– the maximum number of characters the host may send at the same time is 1024.
– for each row, a LF character is cancelled from the source file data (LF=0A hex; the “end of line” character is actually doubled under DOS, being made up of CR and LF characters, while the Z32 only receives the CR).
– Therefore each packet transmitted by the host may be at most 426 rows long.
The limit of 426 rows may be exceeded only if the source file contains many empty rows (even if all rows had only two characters plus CR it couldn’t be possible to exceed 426 rows).

CN1413

It is a protection in the handling of polar axes, to avoid possible operation anomalies too near to the spin center. If during the movement the distance from the center becomes less than 5 mm, an alarm CN1413 is triggered.

CN1513

The CN1513 alarm indicates an anomalous situation where machine axes are interpolated but not “alive”. This may happen when a movement is requested from a non-alive axis too near to the positioning threshold, thus making it move inside and outside the threshold (e.g. because of an axis quota oscillation). A typical example is that of an axis (rolling table) which, during blocking, has a slight movement that brings it near the allowed positioning error, or from which a movement is required which is slightly less than the positioning threshold.

CN1613

The CN1613 alarm signals that the ZSER ring is interrupted.

CN1713

Normally this alarm never appears. Should it appear, please notify D.Electron.

CN1813

The CN1813 alarm is triggered whenever, while sending $% type DNC part-programs (on a serial line), there is a data protocol transmission error, or a block error.

CN1A13

The CN1A13 error appears on machines with process lock under the following conditions:
if one of the related processes triggers an alarm during the lock cycle, the other processes that must interrupted immediately generate this alarm too.

CN1B13

The CN1B13 error appears on machines with process lock under the following conditions:
if one of the master/slave processes is triggered unexpectedly (e.g. when pressing the reset button) the other master/slave process generates this alarm too.

CN1C13

The CN1C13 alarm communicates that at least once, the AT data reading has been carried out with excessive delay (telegrams from the Z-SER linked drives to the Z32 CPU).
As a consequence, this may provoke faulty axis readings (e.g. repeated measures), and therefore faulty motions.

CN1D13

The CN1D13 alarm communicates that at least once, the MDT data writing has been carried out with excessive delay (telegrams from Z32 CPU to the Z-SER linked drives). As a consequence, faulty speed measures may be provided to the drives, therefore leading to faulty motions.

CN1E13

MU type memory alarm. The CN1E13 alarm is triggered whenever a sporadic MU alarm occurs that has not been stored by the PLC: this alarm appears – even for a very short time (a logic cycle) – and then disappears.

CN1F13

This alarm is released when – in the variable pitch threading function (G34/G35) – a pitch lower that or equal to zero is obtained as a consequence of a K decrease (thread pitch).

CN2013

This alarm is released when the NOT live axes to be monitored are outside their position beyond the admissible tolerance limit.

CN2113

PC HARDWARE TOO SLOW.
This alarm appears when the hardware of the PC where Z32 is running is not sufficiently fast for Z32 and some Z32 functionalities can be compromised.

CN2313

This alarm refers to the PCL function FFCOUPLE, used for coupling axes (a slave axis follows a master axis). This alarm appears when requesting a coupling procedure when the slave axis is alive. If the slave axis is alive, the coupling doesn’t takes place and a CN2313 alarm appears both on the master axis process and on the slave alive axis process.

CN2413

This alarm refers to the PCL function FFCOUPLE, used for coupling axes (a slave axis follows a master axis). This alarm appears when the following error of the slave axis is greater than the maximum following error set in the axis settings. In this case, the movement stops and a CN2313 alarm appears both on the master axis process and on the slave alive axis process. For more information, read the specific machine documentation.

CN2513

This alarm refers to the PCL function FFCOUPLE, used for coupling axes (a slave axis follows a master axis).This alarm appears when there is a position transducer error on the master (or the slave) axis and the master (or the slave) axis is defined with zero setting in the settings. In this case a CN2513 alarm appears both on the master axis process and on the slave alive axis process.

CN2613

This alarm refers to the PCL function FFCOUPLE, used for coupling axes (a slave axis follows a master axis). This alarm appears when the master axis (or the slave axis) is in the “zero setting” procedure. The alarm appears both on the master axis process and on the slave alive axis process.

CN2713

The CN2713 alarm appears when the writing procedure of a PRM[ ] parameter inside the CMOS memory was not successful.

CN2813

This alarm appears when programming a movement involving more that 5 interpolating axes while it is active a function not compatible with movements involving more that 5 interpolating axes.

CN2A13

This alarm appears (on all the active processes):
– in the case Z-Star, if one or more peripheral boards (ENC, PWM) have faulty communication with the CNC
– in the case Z-Star2: if one or more servodrives have faulty communication with the CNC
To know the faulty unit:
– in the case Z-Star, read the PLC variable HHBOARDALARM[0] (bit map of the faulty boards installed in the Z-Box 0 to 3) and the variable HHBOARDALARM[1] (bit map of the faulty boards installed in the Z-Box 4 to 7)
– in the case Z-Star2, read the PLC variable HHBOARDALARM[0] (bit map of the faulty servodrives 0 to 32).
The alarm CN2A13 is eliminated by a simple CN RESET if the board error has been removed.

CN2B13

This alarm refers to the G155 (raster-type laser printing). It comes when the mass-memory access (hard-disk) is too slow (printing data not available)

CN2D13

This alarm refers to the G155 (raster-type laser printing). It comes when it is programmed a parameter #P lss than zero when the printing mode is mono-directional.

CN2E13

This alarm may come when in the machine there is an absolute axis, without end-of travel (cyclic axis) and the absolute travel of the motor generates a non-integer number of axis turns. This is a “critical” axis, were the available number of turns in the same direction is limited. This alarm comes if this number is surpassed (in other words, the absolute axis is over ½ of its travel). Please move back manually the axis, so to conduct it in a safe zone.

CN3013

Alarm related to the Profibus management. It comes at turn-on if the Profibus interface boards doesn’t activate in 5 seconds. Probable causes: wiring error or board missing.

CN3113

Alarm related to the Profibus management. It comes at run-time if the Profibus INPUTS are not refreshed for more than 48 mS. Probable causes: uncertain or interrupted connection to the Profibus peripherals.

CN3213

Alarm related to the Profibus management. It comes at run-time if the Profibus OUTPUTS are not refreshed for more than 48 mS. Probable causes: uncertain or interrupted connection to the Profibus peripherals.

CN3313

Excessive following error for gantry system defined by machine settings (Note: the PLCdefined gantry system has a different alarm code). It comes if the following error of the gantry slave axis becomes higher than the “Tolerance when moving” defined for the slave axis in the machine settings.

CN3413

Excessive following error for gantry system PLC-defined (Note: gantry system define by machine settings has a different alarm code). It comes if the following error of the gantry slave axis becomes higher than the “Tolerance when moving” defined for the slave axis in the machine settings.

CN3513

Spindle head has undefined state. This alarm comes in machines equipped with headexchanging system if a CN activity is requested (Automatic, MDI, JOG) before the PLC has defined what head is installed.
Probable cause: the head exchanging system is not well defined or corrupted.

CNCx13

A CNCx13 alarm (x = logical number of alarmed axis) is triggered when permanent formulas are active and an axis exceeds 8.000.000 detector steps relative to the current origin. To give an idea, this corresponds to about 4 meters (12 feet) with the most discretized (i.e. sensitive) detectors the Z32 can handle. The alarm is also released in the case that one of the linear axes XYZ exceeds the limit of 134,217,728 detector steps (referred to the current origin) with G118NHR1 active: with the most sensitive detectors that can be controlled with the Z32, this measure corresponds to about 72 metres.

CNDx13

A CNDx13 alarm (x = logical number of alarmed axis) is triggered when a machine axis is moving with a different speed than what was required by the NC. The NC integrates the speed imposed to the axis and determines the space this must cover, comparing it with the detector’s report; if they are not equal, the NC triggers a CNDx13 alarm. The alarm is active on both continuous and indexed axes.

CNEx13

Where x is the logical number of the continuous axis which triggered the alarm. During the execution of a movement with RTCP, «…» permanent formulae, or tracing, the axis motion controller detected that the axis got dangerously near the end of run. For example, CNE013 indicates end of run error on the axis with logical number 0 (normally the X axis)..

CNFx13

Where x is the logical number of the continuous axis which triggered the alarm. During the execution of a movement with RTCP, «…» permanent formulae, or tracing, the axis motion controller detected an excessive speed on the axis. For example, CNF113 indicates overspeed alarm on the axis with logical number 1 (normally the Y axis).

CNFF13

Error forced after execution of activity 8, speed controlled axis motion. The alarm is automatically cleared upon activity exit.

CN..14 – Machine programming and usage alarms

These alarms indicate a programming error, a program permanent memory storage fault, or an incorrect usage of some activities.
They are usually accompanied by a plaintext explanation on the command line.
The first part of the row where the error was detected precedes the explanation on the command line.
All allowed error messages are listed below.

CN0214 – OUT OF MEMORY

Available program memory has no room available for the requested write operation(s). It is necessary to erase some programs, archiving them on floppy, to make room.

CN0914 – CMOS ERROR …..

Indicates that an error occurred in numerical controller file manipulation. The CMOS error code has the following meanings:
1 too many files open, or file already open;
2 file is not open;
3 pointer beyond end of file;
4 memory full;
5 reading beyond end of file;
6 file not found;
7 file already exists;
13 internal formal error;
14 attempt to read and write on the same file;
20 internal file concatenation error;
21 CMOS variation memory full;
22 physical write into CMOS memory did not terminate successfully.

A block search has been done and the tool in the chuck is different from the one that should be there at that point of the program.
It is necessary to switch to semiauto mode, change the tool and repeat program choice and block search.

CN1A14 – AXIS MOVEMENT ATTEMPT DURING ZERO SETTING

An attempt has been made to launch the jog mode, or an automatic program or a semiautomatic movement, during axis zero setting.

CN1C14 – MISSING %

An attempt has been made to run a main program or a subprogram (or fixed cycle or special M) which has no leading percent sign. With software versions dated after October 4th, 1993 the “%” symbol is no longer mandatory at the beginning of a part program.

CN1D14 – PROGRAM ERROR

The program row being analyzed (showed on the command line before the error message) contains an error:
– undefined G
– excessive M
– incorrect parameter name
– incorrect arithmetical expression
– some other syntax error
The character after the one which triggered the error, if it is inside the displayed part of the row, is shown in inverse video to help locating the error.
If no shown character is displayed in inverse video, this means that the row is too long and the error is contained in the row section that does not fit on the display.

CN2414 – RETURN ERROR

It is an error message related to a return from a series of rows, which should never happen. If it does, notify D.Electron.

CN2514 – BASE ORIGINS ERROR

Base origins are not correct; the file containing the current process’ base origins is missing, or is in memory error, or does not contain the base origins of all of the machine axes.

CN2614 – ADDITIONAL ORIGINS ERROR

Additional origins are not correct; the file where such origins are defined is missing or is in memory error, or the program recalled an additional origin which was not defined in the process origins’ table nor in any local section.

CN2714 – SETUP IMPOSSIBLE

A G111T (copy mode analog feeler setup) has been programmed and the values returned are not correct. This alarm can also appear during the automatic axis setup (activity 11) when detected values are out of tolerance limits. This alarm can also appear during the G125 (axes setup for high speed) if exceptional movement conditions leads to impossible axis setup.

CN2B14 – INCOMPATIBLE PROFILE

CN2E14 – TOO MANY SUBROUTINES

A subroutine call (GON..-N.., GOP.., special Ms, fixed cycles, permanent subprograms, G110, DO cycle) has been made which exceeds the maximum allowed subroutine nesting level.
Since the allowed limit is more than enough for normal uses, this error may indicate that a programming error resulted in a “branch loop” where a subroutine calls itself without returning, thus performing branch on branch until the allotted stack slots are exhausted.

CN2F14 – TOOL

Either the programmed tool or the one on the chuck are not defined in the active tool section, or the related tool section is missing, or the wrong tool is on the chuck.

CN3114 – BEYOND F.C. (Fine Corsa = End Run)

During a program execution, between the block shown as ‘executing’ and the one shown on the command line, a movement has been programmed which is beyond the end run as defined in the machine setup.

CN3214 – PREVIOUS WRONG

In the profile programming the segment preceding the one shown on the command line is of the wrong type (see also the geometry section in the programming manual).

CN3314 – INSIDE CIRCLE

In the profile programming, the segment shown on the command line requires a circle/line tangent which can not be found, since the line starting point is inside the circle, or because the two circles to be joined are either internal or intersecting (see also the geometry section in the programming manual).

CN3414 – PREVIOUS OPEN

In the profile programming the segment preceding the one shown on the command line is open (see also the geometry section in the programming manual).

CN3514 – ROW TOO LONG

CN3B14 – SUBROUTINE WAS MODIFIED

During the automatic execution a subprogram was called that had been modified either through the editor or through external communication.

CN3C14 – G33, G34, G35 or G63 ACTIVE

With G33 (threading), G34/G35 (variable pitch threading) or G63 (rigid tapping) active, an incompatible function has been also programmed (see Programming Manual for further details).
The program has to be modified.

CN4014 – G110 ROW NUMBER NOT FOUND

One of the row numbers (beginning or end) programmed in G110 does not exist in the specified program or subprogram.

CN4114 – G110 SUBROUTINE NOT FOUND

A call to a nonexistent subroutine level has been programmed in G110.

A RB (rounding) has been programmed at the end of this trait, which is an arc of circle.

CN4414 – MISSING INTERSECTION

The programmed trait requires a geometrical intersection which was not found.

CN4514 – RB/RR OVER CONTINUOUS ENTRY

A RB (rounding) or a RR (joint radius) has been programmed at the beginning of this trait, which needed a continuous entry.

CN4714 – FEELER DISCONNECTED

A G111 has been programmed, but the analog copy feeler was not installed (the logic bit is not 1).

CN4B14 – TOO MANY PARAMETERS

Too many two-character user parameters have been put in a part-program (e.g. HA, HB, HC, … up to a maximum of sixty).

CN4C14 – ANSWER ERROR

CN4D14 – SUSPENDED BLOCKS INTERNAL ERROR

CN4E14 – :L DISK FILE ERROR

Related to the :L feature to load/download a disk file on part-program’s command. This means that the DOS program got a read error accessing the selected file. The exact cause of the error is not available, and the error may be due to various causes: file or path not found, disk not ready, disk access error… it is up to the operator to remove the error.

CN4F14 – :L Z32 FILE ERROR

Related to the :L feature to load/download a disk file on part-program’s command. This means that the Z32 got a write error writing to the file. As for CN4E14, there is no additional information; the error may be caused by the memory being full, the file being locked by the Z32, or a write data error. Here too it is up to the operator to remove the error.

CN5014 – UNKNOWN :L ERROR

Related to the :L feature to load/download a disk file on part-program’s command, it indicates a malfunction in the exchange between the Z32 and the support program.
If the DOS program (TERMS in this case) is correct, this type of error should never happen.

CN5114 – AXIS MOTION WITH INCOMPLETE G121 INITIALIZATION

The part-program commanded an axis movement while the G121 initialization had not been completed yet.

CN5214 – G121 LIMITS NOT IN SEQUENCE

The G121 limits defined in the part-program are not in the correct sequence.

CN5314 – INSUFFICIENT PROCESSING POWER

Indicates that the PC processor is not powerful enough to handle the “advanced speed” (G113V).

CN5414 – INCONSISTENT MACHINE SETUP

This alarm is triggered whenever, during a G117, G118, G122, G141, G142 programming, the related axes’ setups are incorrect or do not comply with the required specifications.
This alarm message also appears whenever a G120 is programmed and the use of this function has been inhibited in the PLC.

CN5514 – G123 LIMITS NOT VALID

This alarm is triggered in G123 when a positive limit is programmed which is less than the negative limit.

CN5614 – G123 QUOTA EXCEEDS LIMITS

This alarm is triggered in G123 if the programmed quotas are outside limit quotas.
