PM Vector Control
21.2.2 PM with Encoder - P0202 = 6
The PM with encoder control presents the advantages described for the Sensorless control, plus a speed control
accuracy of 0.01 % (by using the 14-bit analog reference via IOA-01, or by digital references via HMI, Profibus DP,
DeviceNet).
It requires the ENC-01 or ENC-02 accessory for the interface with the incremental encoder.
