r0396 | CO: Act. rotor resistance |
| Min: | - |
| Datatype: Float | Unit: % | Def: | - |
|
| Max: | - |
Level
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).
