(23) Separate detector disconnection alarm ignore signal
NDCAL1<G67#5>, NDCAL2<G71#5>, ...
[Classification] Input signal
[Function] If this signal is 1 in velocity command mode, no alarm is issued in the
event of a hardware disconnection in the separate detector.
If the signal changes from 1 to 0, the internally held status information
about a hardware disconnection alarm is cleared.

The servo software does not issue a
hardware disconnection alarm during
this period.
NOTE
1 This signal must be changed from 1 to 0 before
switching occurs from the velocity command to the
position command.
2 Once switching occurs from the velocity command to
the position command, make a manual reference
position return before the axis is moved.
3 This function cannot be used with an absolute position
detector.
4 To enable this signal, set parameter HNG (bit 4 of
parameter No. 1959) to 1.
(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.
