5.2.10.6 PM Settings
If [2] Std. PM, non-salient is selected in parameter 1-10 Motor Construction, enter the motor parameters manually in the following
order:
• Parameter 1-24 Motor Current.
•
Parameter 1-26 Motor Cont. Rated Torque.
•
Parameter 1-25 Motor Nominal Speed.
•
Parameter 1-39 Motor Poles.
•
Parameter 1-30 Stator Resistance (Rs).
•
Parameter 1-37 d-axis Inductance (Ld).
• Parameter 1-40 Back EMF at 1000 RPM.
The following parameters have been added for PM motors.
•
Parameter 1-41 Motor Angle Offset.
•
Parameter 1-07 Motor Angle Offset Adjust.
• Parameter 1-14 Damping Gain.
• Parameter 1-47 Torque Calibration.
• Parameter 1-58 Flying Start Test Pulses Current.
• Parameter 1-59 Flying Start Test Pulses Frequency.
•
Parameter 1-70 Start Mode.
•
Parameter 30-20 High Starting Torque Time [s].
•
Parameter 30-21 High Starting Torque Current [%].
Standard parameters still need configuration (for example parameter 4-19 Max Output Frequency).
