Rated voltage of motor
P31.10 Slip compensation gain
Used under V/f control. When the motor is driving an electric-driven load, motor speed drops
with the increase of load. When the motor is driving a power generating load, motor speed will
increase with the increase of load. Appropriate slip compensation gain can maintain constant
motor speed when the motor load is changing.
To ensure the performance of slip compensation gain, setting motor rated speed P30.06 is
essential. The difference between P30.06 and the motor running speed without load is the
rated slip. Through real-time detection of motor load, slip compensation automatically adjusts
the drive output frequency on the basis of rated slip and motor load, reducing the impact of
changing load on motor speed.
Gain adjustment method: please make the adjustment around 100%. When motor is
driving an electric-driven load: if motor speed is relatively lower, the gain should be
appropriately increased; if motor speed is relatively higher, reduce the gain appropriately. When
motor is driving a power generating load: if motor speed is relatively lower, the gain should be
decreased; if motor speed is relatively higher, increase the gain appropriately.
Diagram of slip compensation gain is shown as Fig. 5-39 and 6-45.
