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 current feed value or the machine feed value overflows or
underflows during deceleration, the manual pulse generator operation will
terminate as "error occurring". To carry out manual pulse generator operation
again, "
