[Pr.24] Manual pulse generator/Incremental synchronous encoder input selection
Set the manual pulse generator/incremental synchronous encoder input pulse mode.
Manual pulse generator/Incremental synchronous encoder input selection
A-phase/B-phase multiplied by 4
A-phase/B-phase multiplied by 2
A-phase/B-phase multiplied by 1
PULSE/SIGN
Set the positive logic or negative logic in "[Pr.151] Manual pulse generator/Incremental synchronous encoder input logic
selection".
■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-phase/B-phase multiplied by 4
The positioning address increases or decreases at rising or falling edges of A-phase/B-phase.
