(1) Phase A/Phase B
• Input the pulse signal from the manual pulse generator/incremental
synchronous encoder 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.
