Operations when stroke limit error occurs
When the hardware stroke limit error or the software stroke limit error is detected
*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
*1
.
After stopping, manual pulse generator input pulses to the outside direction of the limit range are not accepted, but operation
can be executed within the range.
*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, "[Cd.21] Manual pulse generator
enable flag" must be turned OFF once and turn ON.
Operation timing and processing time
The following drawing shows details of the manual pulse generator operation timing and processing time.
