(3) Precautions during operation
The following details must be understood before carrying out manual pulse generator operation.
• The speed during manual pulse generator operation is not limited by the "[Pr.8] Speed limit value".
• If the "[Cd.21] Manual pulse generator enable flag" is turned ON while the LD75 is BUSY (BUSY signal ON),
the warning "Start during operation" (warning code: 100) will occur.
• If a stop factor occurs during manual pulse generator operation, the operation will stop, and the BUSY signal
will turn OFF. At this time, the "[Cd.21] Manual pulse generator enable flag" will be left ON, but manual pulse
generator operation will not be possible. To carry out manual pulse generator operation again, measures
must be carried out to eliminate the stop factor. Once eliminated, the operation can be carried out again by
turning the "[Cd.21] Manual pulse generator enable flag" ON
OFF
ON. (Note that this excludes when
hardware/software stroke limit error occurs.)
• Pulses will not be output if an error occurs when the manual pulse generator operation starts.
Remark
●
One LD75 module can be connected to one manual pulse generator.
●
The LD75 module can simultaneously output pulses to the axis 1 to axis 4 drive units by one manual pulse generator. (1-
to 4-axis simultaneous operation is possible.)
(4) Operations when stroke limit error occurs
When the hardware stroke limit error or the software stroke limit error is detected during operation, the operation
will decelerate to a stop. However, "[Md.26] Axis operation status" will keep the status "Manual pulse generator
operation" in that case.
*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 current machine feed value overflows or underflows during deceleration, the
manual pulse generator operation will terminate as "[Md.26] Axis operation status" is changed to "Error". To carry out
manual pulse generator operation again, "[Cd.21] Manual pulse generator enable flag" must be turned OFF once and
turn ON.
