Adjustment procedure
1. Select PM motor control
Pr.05-33 Induction Motor (IM) or Permanent Magnet Synchronous Motor Selection =1 (SPM)
or 2 (IPM)
2. Set up motor parameters according to the motor’s nameplate
Pr.01-01: Rated frequency
Pr.01-02: Rated voltage
Pr.05-34: Rated current
Pr.05-35: Rated Power
Pr.05-36: Rated speed
Pr.05-37: Number of poles for the motor
3. Execute PM Auto-tuning (static)
Set Pr.05-00 Motor Parameter Auto-Tuning =13 (High frequency stall test for PM synchronous
motor) and press RUN.
When you finish tuning, the following parameters are available:
Pr.05-39: Stator resistance
Pr.05-40: Permanent magnet motor Ld
Pr.05-41: Permanent magnet motor Lq
Pr.05-43: (V / 1000 rpm), the Ke parameter of PM motor (you can calculate this automatically
according to power, current, and speed of the motor).
Pr.10-52: The amplitude of the high frequency signal injected during angle detection.
4. Set the speed control mode: Pr.00-10 Control Mode = 0, Pr.00-11 Speed Control Mode = 2
SVC.
5. Cut off the power after you finish tuning, and then restart.
6. The ratio of the PMSVC control mode is 1:20.
7. When the PMSVC control mode is under 1/20th of the rated speed, the load bearing capacity
is 100% of the motor rated torque.
8. PMSVC control mode is not applicable to zero speed control.
9. Start-up with load and forward/reverse load bearing capacity of PMSVC control mode equal
to 100% of the rated torque of motor.
10. Set up the speed estimators related parameters.
Pr.10-31 I/F Mode, Current Command
Pr.10-32 PM FOC Sensorless Speed Estimator Bandwidth
Pr.10-34 PM Sensorless Speed Estimator Low-pass Filter Gain
Pr.10-42 Initial Angle Detection Pulse Value
Pr.10-49 Zero Voltage Time during Start-up
Pr.10-51 Injection Frequency
Pr.10-52 Injection Magnitude
Pr.10-53 Position Detection Method
11. Speed adjustment parameter
Pr.07-26 Torque Compensation Gain
