P4.09 V/F SLIPCOMP 0.00~10.00Hz 0.00~10.00 0.0Hz
The motor’s slip changes with the load torque, which results in the variance of motor
speed. The inverter’s output frequency can be adjusted automatically through slip
compensation according to the load torque. Therefore the change of speed due to the
load change can be reduced. The value of compensated slip is dependent on the motor’s
rated slip which can be calculated as below:
P4.09 

f
b
 n * P / 60
Where motor rated frequency (P2.01) is,
n
is motor rated speed (P2.02), and
P
is
pole pairs of motor.
