(24) PMC axis overtravel signals
+EOT1<F65#6>, +EOT2<F69#6>, ...
-EOT1<F65#7>, -EOT2<F69#7>, ...
[Classification] Output signal
[Function] If an overtravel alarm condition is detected,
When the positive-side stroke limit is exceeded:
Positive direction signal +EOTx becomes 1.
When the negative-side stroke limit is exceeded:
Negative direction signal -EOTx becomes 1.
To reset the alarm, perform either of the following operations.
1 Resetting an alarm in PMC axis mode
First set the reset signal RSTx to 1, then reset it to 0. This resets
the overtravel signal to 0.
Move the axis to within the stroke limit using the PMC axis
control command, then reset the CNC.
Only the following commands can be used to move the axis back
to within the stroke limit while an overtravel alarm condition
exists.
(1) Rapid traverse (CDxX7 to CDxX0: 00h)
(2) Cutting feed--feed per minute (CDxX7 to CDxX0: 01h)
(3) Cutting feed--feed per revolution (CDxX7 to CDxX0: 02h)
(4) Continuous feed (CDxX7 to CDxX0: 16h)
2 Resetting an alarm in CNC axis mode
Reset the signal PCAXx to 0 to switch to the CNC axis. This
resets the overtravel signal to 0.
Move the axis to within the stroke limit using a CNC axis move
command (such as manual continuous feed or handle feed), then
reset the CNC.
In the above case, use the reset button on the MDI panel, the
external reset signal ERS, or emergency stop signal *ESP, rather
than the reset signal RSTx, to "reset the CNC."
