Dependent Setting (Menu Index 4.4.4)
P 4.4.4.1 Slip Comp. Gain
Enter the % value for slip compensation to compensate for tolerances in the value of n
M,N
. Slip compensation is calculated automatically,
that is, based on the rated motor speed n
M,N
. This function is not active when P 5.4.2 Configuration Mode is set to [1] Speed closed loop ,
[2] Torque closed loop , or [4] Torque open loop , or when P 5.4.3 Motor Control Principle is set to [0] U/f , or when P 4.2.1.1 Motor Type is
set to [1] PM, Non-salient SPM or [3] PM, Salient IPM .

P 4.4.4.2 Slip Comp. Time Constant
Enter the slip compensation reaction speed. A high value results in slow reaction, and a low value results in quick reaction. If low-
frequency resonance problems occur, use a longer time setting.

P 4.4.4.3 High Speed Load Comp.
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.
