Push-pull type encoder output
Diagram assumes normal pulse order in Forward
rotation: Pulse A/1 leads as diagrammed on the
right.
For encoders with pulse 2 leading, change the diagram for these
connections:
• Encoder A/1 and B/2 should be wired to MTAC terminals B and A,
respectively.
• Encoder A/1 and B/2 (if present) should be wired to MTAC terminals
B and A, respectively.
