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 [%] .
N O T I C E
Standard parameters still need configuration (for example parameter 4-19 Max Output Frequency ).
