Outline of manual pulse generator operation

1. Operation
When selecting the MPG (manual pules generator operation) in the operation patterns, the 20SSC-H
operates by the MPG input at the START commnand ON.

Manual pulse generator input
End of positioning
Note
• The manual pulse generator inputs the pulses in two phases (A-/B-phase).
• The positioning completion flag does not turn ON.
• When reaching the forward/reverse rotation limit during forward/reverse rotation, a forward/reverse rotation
limit error occurs.
Perform reverse rotation if the forward rotation limit is ON, or perform forward rotation if the reverse rotation
limit is ON to cancel a limit switch ON-state.
Perform reverse rotation manual pulse generator
operation or perform JOG operation to cancel a
limit error.
• The manual pulse generator input two-phase pulses (A-/B-phase) at 1 edge count.
- Only the differential output type manual pulse generator is connectable.
- Operation at the manual pulse generator is always counted.
See the "current MPG (manual pulse generator) input value" to monitor in modes other than the manual
pulse generator operation mode.
