1-61 High Speed Load Compensation
Default value:
100%
Setup: All setups
Data type:
Int16
Parameter 1-61 High Speed Load Compensation only has effect when parameter 1-10 Motor Construction = [0] Asynchron.
Enter the % value to compensate voltage in relation to load when the motor is running at high speed and obtain the optimum U/f
characteristic. The motor size determines the frequency range within which this parameter is active.

1-62 Slip Compensation
Default value: Size related
Setup: All setups
Data type: Int16
Enter the % value for slip compensation to compensate for tolerances in the value of n
that is on the basis of the nominal motor speed n
Speed closed loop or [2] Torque torque control with speed feedback or when parameter 1-01 Motor Control Principle is set to [0] U/f.
