use a line-driver output type encoder. This is required for PG vector control, position control, or torque
control operation.
For details on the PG Board, refer to PG Board 3G3AX-PG User’s Manual (I564).
The PG Board can be mounted on the option port 1 or 2. Securely mount the PG Board as shown
below.
Place the four holes in the corners of the PG Board; two holes on the guideposts and the other two on
the screw holes. Put the connector at the back of the PG Board on the option port 1 or 2 correctly.
Then, tighten the two fixing screws for the PG Board securely.
