Manual Pulse Generator Operation
Outline of manual pulse generator operation
Operation
In manual pulse generator operations, pulses are input to the Simple Motion module from the manual pulse generator. This
causes the same number of input command to be output from the Simple Motion module to the servo amplifier, and the
workpiece is moved in the designated direction.
The following shows an example of manual pulse generator operation.
1.
When "[Cd.21] Manual pulse generator enable flag" is set to "1", the BUSY signal turns ON and the manual pulse
generator operation is enabled.
2.
The workpiece is moved corresponding to the number of pulses input from the manual pulse generator.
3.
The workpiece movement stops when no more pulses are input from the manual pulse generator.
4.
When "[Cd.21] Manual pulse generator enable flag" is set to "0", the BUSY signal turns OFF and the manual pulse
generator operation is disabled.

*1 If the input from the manual pulse generator stops or "0" is set in "[Cd.21] Manual pulse generator enable flag" during manual pulse
generator operation, the machine will decelerate to a stop within 25 ms.
*2 The start complete signal does not turn ON in manual pulse generator operation.
• Create the program so that "[Cd.21] Manual pulse generator enable flag" is always set to "0" (disabled)
when a manual pulse generator operation is not carried out. Mistakenly touching the manual pulse
generator when the "manual pulse generator enable flag" is set to "1" (enable) can cause accidents or
incorrect positioning.
• A manual pulse generator is required to carry out manual pulse generator operation.
