2.3.4 Motor shaft Feedback device (Encoder) wiring details
a) Following steps should be followed in encoder wiring:
 PG wire should be laid separately in pipe and metal enclose should be grounded and keep
distance from the control circuit and driver circuit
 PG wire should be shield wire and shield layer should connect to PE near controller. In order
to avoid being disturbed, only one side of the PG Grounding wire should be connected to the
ground
b) Encoder Wiring Details:
1. Encoder connection for increment Push-Pull and Plough collector outputs
MCTC-MCB-G equipped with push-pull encoder trans-connection card, the encoder connection is
as follows
