• If high accuracy sensorless control is required, set P.300 to 3 for sensorless vector control.
Note: 1. The motor capacity has to be at the same level or one level below of the level of the capacity of
the inverter.
2. For the auto-tuning function, if motor operation is permitted, set P.301 to 1 (dynamic
measurement). At this point, the load has to be separated from the motor. If the load environment
