3

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).
