Chapter 11 Manual Control
Operations when stroke limit error occurs
When the hardware stroke limit error or the software stroke limit error is detected
(Note-1)
during operation, the operation will decelerate to a stop. However, in case
of "[Md.26] Axis operation status", "Manual pulse generator operation" will
continue
(Note-1)
. After stopping, input pulses from a manual pulse generator to
the outside direction of the limit range are not accepted, but operation can be
executed within the range.
(Note-1): Only when the feed current value or the feed machine value overflows or
underflows during deceleration, the manual pulse generator operation will
terminate as "error occurring". To carry out manual pulse generator operation
again, "[Cd.21] Manual pulse generator enable flag" must be turned OFF once
and turn ON.
