Wiring Diagrams
Push-Pull Type Encoder Output
Diagram assumes normal pulse order in Forward rotation: Pulse A/1 leads as
diagrammed below
For encoders with pulse 2 leading, change diagram for these connections:
• Encoder A/1 and B/2 should be wired to OTAC terminals B and A respectively.
• Encoder A/1 and B/2 (if present) should be wired to OTAC terminals B and A
respectively.
Differential connection
Single-ended connection
Note 1: Connect the cable shield at the encoder housing, if, and only if, the
encoder is isolated from the motor, and from ground.
