 Open collector type, push-pull output type encoder wiring:
Select the encoder power supply through SW3 on the PG card, SW1 and SW2 to the OC side, as
shown below:：
Chart 7-5 Collector open type, push-pull output type encoder DIP switch selection
When wiring, the A-、B-、Z- terminals of the PG card are not wired, and the signal output of the
encoder is connected to the A+、B+、Z+ terminals of the PG card, as shown in the figure below.：
