[Pr.24] Manual pulse generator/Incremental synchronous encoder input
selection
Set the manual pulse generator/incremental synchronous encoder input pulse
mode. (Only the value specified against the axis 1 is valid.)
0: A-phase/B-phase multiplied by 4
1: A-phase/B-phase multiplied by 2
2: A-phase/B-phase multiplied by 1
3: PLS/SIGN
Set the positive logic or negative logic in "[Pr.22] Input signal logic selection".
(1) A-phase/B-phase mode
• When the A-phase is 90° ahead of the B-phase, the motor will forward run.
• When the B-phase is 90° ahead of the A-phase, the motor will reverse run.
(a) A-phase/B-phase multiplied by 4
The positioning address increases or decreases at rising or falling edges
of A-phase/B-phase.
