Special adjustment parameter group13
PARAMETER DESCRIPTION 292
5.14.1 Slip compensation
V/F
This parameter can set the compensation frequency and make the running speed of the motor at the rated current is
closer to the set running speed, thus improving the accuracy of speed control.

0: Off.
10: The compensation value is 3% of the target frequency.
Note: 1. This function is only valid in V/F mode (00-21(P.300)=”0”).
2. At the process of slip compensation, the output frequency may be larger than the set frequency
5.14.2 Modulation coefficient
It is used to determine the ratio of the maximum output voltage to the input voltage.

Maximum output voltage =“13-01(P.246)” × input voltage
Modulation coefficient
This parameter can be used to obtain the maximum output voltage higher than the input voltage.
However, if the set value is higher, the waveform of the output voltage will be distorted and contain harmonic
waves, thus increasing the torque harmonics and noise of the motor.
