Connection Of Motor With Encoder (Vector Control) - Mitsubishi Electric FR-A720-0.4K Instruction Manual

2.4 Connection of motor with encoder (vector control)

Orientation control and encoder feedback control, and speed control, torque control and position control by full-scale
vector control operation can be performed using a motor with encoder and a plug-in option FR-A7AP.
