Does RFR parameter show the output frequency of the drive to the motor, or the actual motor speed?

Issue:
Does the RFR parameter in the ATV71 drive show the output frequency of the drive to the motor, or the actual motor speed?

Product Line:
Altivar 71 series

Environment:
All models, All serial numbers.

Cause:
Customer wants to monitor the true output speed of the drive to the motor while in torque limitation mode but RFR seems to show the actual motor speed.

Resolution:
RFR always shows an estimation of the actual motor speed and not the output frequency of the drive to the motor.  The only way to have RFR show the actual output frequency to the motor is to set Slip Compensation to 0%.  This will also have the effect of reducing the available torque of the motor.
