5. Set ASR Parameters
Pr11-00 bit0=1:
Pr11-02
ASR1/ASR2 Switch Frequency
10Hz.
Pr11-03
ASR1 Low-speed Bandwidth
Low-speed Bandwith too high to avoid dissipation of the estimator.
6. Set speed estimator and speed control's parameter.
Pr10-39
Frequency when switch from I/F Mode to PM sensorless mode.
Pr10-32
PM Sensorless Obeserver Bandwith for High Speed Zone
