Outline of manual pulse generator operation

1. Operation
When selecting the MPG (manual pulse generator operation) in the operation patterns, the 20SSC-H
operates by the MPG input.

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, the work piece stops
immediately and 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.
