HAH 1A17 (1) A-phase/B-phase
(A+) • 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.

(2) PULSE/SIGN
Input the pulse signal for counting the increased/decreased pulse in the pulse input (PULSE). Input the
signal for controlling forward run and reverse run in the direction sign (SIGN).
1) "[Pr.151] Manual pulse generator/Incremental synchronous encoder input logic selection" is positive logic
• The motor will forward run when the direction sign is HIGH.
• The motor will reverse run when the direction sign is LOW.
2) "[Pr.151] Manual pulse generator/Incremental synchronous encoder input logic selection" is negative logic
• The motor will forward run when the direction sign is LOW.
• The motor will reverse run when the direction sign is HIGH.
