Restricted items
A manual pulse generator is required to carry out manual pulse generator
operation.
Precautions during operation
The following details must be understood before carrying out manual pulse
generator operation.
(1) The speed during manual pulse generation operation is not limited by the
" Pr.7 Speed limit value".
(2) If the " Cd.22 Manual pulse enable flag" is turned ON while the AD75 is BUSY
(BUSY signal ON), a warning "Start during operation" (warning code: 100) will
occur.
(3) 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.22 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.22 Manual pulse generator enable flag" ON
(4) Pulses will not be output if an error occurs when the manual pulse generator
operation starts.
REMARK
•
One AD75 module can be connected to each manual pulse generator axis.
•
The AD75 module can simultaneously output pulses to the axis 1 to axis 3 drive
units by one manual pulse generator.
(1-axis to 3-axis simultaneous operation is possible.)
Errors during operation
When the operation is stopped by the stroke limit (limit switch OFF), manual pulse
generator operation can be performed in the direction in which the limit switch
turns ON after an error reset. (An error will occur again if pulse input is provided in
the direction in which the limit switch turns OFF is turned ON.)
