101 SOFT LIMIT

Cause
Some mistake in operations during the automatic operation has caused the tool tip to overstep the area specified in the software limit parameters in the direction of the axis corresponding to the displayed axis name.
Action
Modify the program so that the tool tip may move within the area specified in the software limit parameters.

113 OVER TRAVEL

Cause
The tool tip has reached stroke limit in the direction of the axis corresponding to the displayed axis name.
Action
Move the tool tip away from the end in manual operation mode.

125 ILLEGAL AXIS EXISTS

Cause
During reference-point return, the proximity-point detection limit switch has overrun the position in which the watchdog is mounted.
Action
Either extend the length of the proximity-point watchdog or reduce the reference-point returning speed. After that, carry out the zero-point returning operation once again.

126 AXIS HAS NOT PASSED Z PHASE

Cause
During initial reference-point return following the power-on action, an axis has not passed through the Z phase of the corresponding detector.
Action
First actuate the handle for manual pulse feed to move the axis back in the opposite direction to the zero-point, and then carry out the zero-point returning operation once again.

127 ILLEGAL DIR. FOR ORIGIN RETURN

Cause
The axis-movement direction selected with the axis selector button is not correct for the reference-point return in manual operation mode.
Action
Set the correct direction (+, –) using the axis selector buttons.

128 OUTSIDE INTERLOCK AXIS

Cause
An axis is interlocked because the interlock function has become active (input signal has turned off).
Action
Clear the active state of the interlock function.

129 INSIDE INTERLOCK AXIS

Cause
The very direction in which the manual skip function has become effective is specified in the axis-movement command. Or the servo-off function is active.
Action
Deactivate the servo-off function.

130 NO OPERATION MODE

Cause
This message is displayed in the event of incorrect mode selection or a mode selector switch malfunction.
Action
Contact Mazak Technical Center or Technology Center.

131 CUTTING FEED OVERRIDE ZERO

Cause
The cutting-feed override value is set to 0 on the machine operating panel.
Action
Change the cutting-feed override value to one greater than 0. If this alarm message is displayed when the cutting-feed override value is not 0, check the signal line for a short-circuit.

132 FEEDRATE ZERO

Cause
An attempt has been made to execute an axis movement in the cutting feed mode or dry-run in the automatic operation mode, with the manual feedrate remaining set to 0 on the machine operating panel.
Action
Change the manual feedrate to a value greater than 0. If this alarm message is displayed when the manual feedrate is not 0, check the signal line for a short-circuit.

141 EXCESS SIMULTANEOUS ERROR

Cause
The synchronization error between the master axis and the slave axis during synchronous control has overstepped a predetermined allowable value.
