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 "Manual pulse generator enable flag (RY(n+2)9, RY(n+4)9)" is turned
ON while the D75P2 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 "Manual pulse generator enable flag (RY(n+2)9, RY(n+4)9)"
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 "Manual pulse generator enable flag (RY(n+2)9,
RY(n+4)9)" ON
OFF ON.
(4) Pulses will not be output if an error occurs when the manual pulse generator
operation starts.
REMARK
One D75P2 module can be connected to each manual pulse generator axis.
The D75P2 module can simultaneously output pulses to the axis 1 to axis 2 drive
units by one manual pulse generator.
(2-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 after an error reset in the direction in which
the limit signal turns ON. (The error will occur again if pulse input is provided in the
direction in which the limit signal turns OFF.)
