PM Sensorless Adjustment Procedure

1. When using high frequency standstill VFD parameter tuning, use VFD software v1.45 to
monitor adjustment procedure. To download VFD Sotware v1.45. go to:

2. Testing PM High Frequency Standstill VFD (calculation of Rs, Ld, Lg)
Procedures:
A. Set control mode as VF mode (Pr00-10=0, Pr00-11=0
B.
Output Frequency of Motor 1
C.
Output Voltage of Motor 1
D.
Induction Motor and Permanent Magnet Motor Selection (Pr05-33=1)
E.
Full-load current of Permanent Magnet Motor(Pr05-34
F.
Set Moto Auto Tuning Pr 05-00 =13;
run the drive.
3. Set control mode as PM sensorless Mode (Parameters 00-10=0, 00-11=6)
4. Set VFD Prameters
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. 設定 ASR 參數 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
7. Zero-load test
Refer to switch point prodcedure of I/F and FOC as shown in the image below.
