Description: Displays stator resistance calculated in [%] from IGBT ON voltage and current amplitude.
Note:
Description:
Displays stator resistance of motor as [%] of combined stator/cable resistance.
Note:
Description:
Displays (adapted) rotor resistance of the motor equivalent circuit (phase value) in [%].
Notice: Values greater than 25 % tend to produce excessive motor slip.
Check rated motor speed [rpm] value (P0311).
