r0395

CO: Total stator resistance [%]

P-Group: MOTOR
Displays the actual stator resistance (combined stator/cable resistance) of the motor as a [%] as a function
of the actual stator winding temperature.
Note:
Actual stator winding temperature, refer to r0632

r0396 CO: Act. rotor resistance
P-Group: MOTOR
Displays the actual rotor resistance of the motor equivalent circuit diagram (phase value) as a [%] as a
function of the actual rotor winding temperature.
Note:
- Actual rotor winding temperature, refer to r0633
- Values greater than 25 % tend to produce excessive motor slip. Check rated motor speed [rpm] value
(P0311).
