PM Sensorless Adjustment Procedure
1. When using high frequency standstill VFD parameter tuning, use VFD software to monitor
adjustment procedure. To download VFD Sotware go to:
http://www.delta.com.tw/product/em/download/download_main.asp?act=3&pid=1&cid=1&tpid=3
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
0000~FFFFh
