Wiring for PG Option Unit

To use PG vector control with this inverter, you need to mount and wire the PG Option Unit
3G3AX-RX2-PG01. Then, install a detector (encoder) to the motor rotating shaft and wire it to the PG
Option Unit. For the detector (encoder), use a line-driver output type encoder. This is required for PG
vector control, position control, or torque control operation.
