run the drive.
3. Set control mode as PM sensorless Mode (Parameters 00-10=0, 00-11=6)
4. Set VFD Parameters
Pr05-35 Rated Power of Permanent Magnet Motor
Pr05-36 Rated speed of Permanent Magnet Motor
Pr05-37 Pole number of Permanent Magnet Motor
Pr05-38 Inertia of Permanent Magnet Motor
5. Set ASR Parameters
Pr11-00 bit0=1: Auto tuning for ASR and APR
Pr11-02ASR1/ASR2 Switch Frequency, it is recommended to set Pr10-39 higher than
10Hz.
Pr11-03: ASR1 Low-speed Bandwidth and Pr11-03, ASR2 High-speed Bandwidth. Do not set
Low-speed Bandwidth too high to avoid dissipation of the estimator.
6. Set speed estimator and speed controls parameter.
Pr10-39 Frequency when switch from I/F Mode to PM sensorless mode.
Pr10-32 PM Sensorless Observer Bandwidth for High Speed Zone
7. Zero-load test
Refer to switch point procedure of I/F and FOC as shown in the image below.
