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:
http://www.delta.com.tw/product/em/drive/ac_motor/download/software/VFDSoft%20v1.45.zip
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;
Then run the drive.
3. Set control mode as PM sensorless Mode (Parameters 00-10=0, 00-11=6)
4. Set VFD Prameters
