11 MANUAL CONTROL
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 generator 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) Position/speed commands will not be output if an error occurs when the
manual pulse generator operation starts.
(5) The pulses input from the manual pulse generator are multiplied by 4.
REMARK
•
One AD75 module can be connected to each manual pulse generator axis.
•
The AD75 module can simultaneously output position/speed commands to the axis
1 to axis 3 servo amplifiers 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 signal OFF), manual pulse
generator operation can be performed in the direction in which the limit signal turns
ON after an error reset. (An error will occur again if pulse input is provided in the
direction in which the limit signal turns OFF is turned ON.)
