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, and Z terminals of the PG card, as shown in the figure below.：

◆
Differential output encoder wiring：
Select the encoder power supply through SW3 on the PG card, SW1 and SW2 to the TP side, as
shown below：
Chart 7-7 Differential output type encoder DIP switch selection
The wiring of the PG card and the encoder are connected one by one according to the silkscreen.
