7.2.1 Sensorless Vector Control Operation for PM motor
To operate a PM synchronous motor in sensorless vector control mode, set DRV-09 (Control
Mode) to 4 (PM Sensorless), select the motor capacity at MOT-01 (Motor Capacity), and enter the
appropriate parameters in the motor (MOT) group with the motor specification values found on the
motor’s name plate. If a specific motor capacity does not exist in the setting options, select a
higher motor capacity that is closest to the actual motor capacity.
