Haas Parameter 278 COMMON SWITCH 3 – Haas Lathe
Parameter 278 is a collection of general purpose single bit flags used to turn some functions on and off. Left and right cursor arrows are used to select function to change. All values are 0 or 1 only. Function names are:
- 0 INVERT G.B. – Default 0. Setting to 1 inverts discrete inputs sense for SP HIGH and LOW (high and low gear).
- 1 UNUSED .
- 2 UNUSED .
- 3 CHK HIDDN MACRO VAR .
- 4 DISPLAY ACTUAL rpm – When set to 1, displays actual spindle speed on Current Commands display page.
- 5 TSC PURGE ENABLE .
- 6 HYDRAULIC TAILSTOCK – Enables the hydraulic tailstock.
- 7 SPINDLE DRIVE LOCK – Must be set to 0 if machine is equipped with a Haas vector spindle drive.
- 8 CHUCK OPEN CSTART – When set to 1, the user can press Cycle Start and run a program with the chuck unclamped. If the spindle is commanded with this bit set to 1, the spindle will not exceed the Chuck Unclamp rpm (Parameter 248). This feature is ineffective when the CE safety circuit is enabled.
- 9 CONCURRENT SPINDLE – When set to 0, spindle start occurs at the end of a block, as in normal M code operation. When set to 1, spindle start occurs at the beginning of a block and concurrent with axis motion.
- 10 TL SET PROBE – Must be set to 1 in order to enable the Tool Pre-Setter.
- 11 HAAS VECTOR DRIVE – Must be set to 1 if machine is equipped with a Haas vector spindle drive. When set to 1, voltage to the vector drive is displayed in the diagnostics display as DC BUSS.
- 12 uP ENCLOSURE TEMP (Microprocessor enclosure temperature) – When set to 1, enclosure temperature will be displayed on INPUTS2 screen of the diagnostics display.
- 13 HAAS REMOTE JOG HDL (Haas remote jog handle) – Must be set to 1 if the machine is equipped with a Haas 5-axis Remote jog handle.
- 14 SPIN MOTOR OTEMP NC (Spindle Motor Over Temperature Normally Closed) – Type (normally open/normally closed) of spindle temperature sensor. Set to 1 for machines with Haas vector drive; 0 for machines without.
- 15 SUBSP TMP NC (Subspindle Temperature Sensor Normally Closed) – Type, (normally open/normally closed) of the subspindle temperature sensor.
- 16 UNUSED .
- 17 NO MFIN CKPU – When it is set, it will prevent checking of MFIN at power-up.
- 18 DEL:Y SWITCH ENABLE (Delta Wye switch enable) – Used for machine with vector drive. If switch is set, but bit 19 is not, winding switching is only done when spindle is at rest, depending on the spindle target speed.
- 19 DEL:Y SWITCH ON FLY (Delta Wye switch enable) – Used for machine with a vector drive. This parameter enables switching on the fly, as the spindle motor is accelerating or decelerating through the switch point.
- 20 CHK BARFEED STATUS – Added for improved Bar Feeder interface. When set to 1, control constantly checks Bar Feeder Status on discrete input 1027. If this input goes high, Alarm 450, Bar Feeder Fault will be generated and the servos and spindle will be turned off. Note that the spindle will simply coast to a stop.
- 21 CHK BF SPIND I-LOCK – Added for improved Bar Feeder interface. When set to 1, the control constantly checks the Bar Feeder Spindle Interlock on discrete input 1030. If this input goes high, and the spindle is being commanded to turn, or coasting or being manually turned at 10rpm or more, Alarm 451, Bar Feeder Spindle Interlock is generated and servos and spindle are turned off. Note that the spindle will simply coast to a stop.
- 22 UNUSED .
- 23 UNUSED .
- 24 LIVE TOOLING – Bit = 1 for lathes fitted with Live Tooling. For all other lathes, this bit is set to 0.
- 25 SUBSPINDLE – Enables G14, G15, M143, M144, M145. Must be set to 1 for lathes with subspindle. When set to 1, control displays Function Locked when Auto All Axes, Home G28, or Power Up/Restart button is pressed.
- 26 C AXIS DRIVE – Enables M154 and M155. It must be set to 1 for all lathes with the C-axis.
- 27 UNUSED .
- 28 VSMTC ENABLE .
- 29 DOOR SAFETY SW INV – Supports CE door interlock that locks when power is turned off. For machines with door lock that locks when power is applied, set bit to 0. For machines with inverted door lock, set bit to 1.
- 30 UNUSED .
- 31 INV SPIND SPD DECEL (Inverse spindle speed deceleration) – When this parameter is set to 1, the spindle decelerates faster at lower speeds, resulting in a shorter deceleration time.
