1-30 Stator Resistance (Rs)
Default value: Size related
Setup: All setups
Data type: Uint32
Set the line-to-common stator resistance value. Enter the value from a motor datasheet or perform an AMA on a cold motor.
This parameter cannot be adjusted while the motor is running.
The parameter value is updated after each torque calibration if option [3] 1st start with store or option [4] Every start with store is
selected in parameter 1-47 Torque Calibration.
1-31 Rotor Resistance (Rr)
Default value: Size related
Setup:
All setups
Data type: Uint32
Parameter 1-31 Rotor Resistance (Rr) has no effect when parameter 1-10 Motor Construction is set to [1] PM, non-salient SPM, [2]
PM, salient IPM, [5] SynRM, and [6] PMaSynRM.
