• Input the pulse signal from the manual pulse generator A phase and B
phase.
• If the A phase leads the B phase, the positioning address will increase at the
rising and falling edges of each phase.
• If the B phase leads the A phase, the positioning address will decrease at the
rising and falling edges of each phase.

• Input the zero signal for machine OPR.
Use the pulse encoder's zero signal and so on.
• Also use this signal when the machine OPR method is the stopper method
and the OPR complete is input from an external source.
• The zero signal is detected at turning from OFF to ON.
