V/F slip
compensation gain
of motor 1
This function code is used to compensate for the motor
speed changes occurred during load variation in
SVPWM control mode, thus improving the rigidity of
mechanical characteristics of motor. Rated slip
frequency of the motor should be calculated.
△f=fb-n×p/60
of which: fb is rated motor frequency, corresponds to
P02.02; n is rated motor speed, corresponds to P02.03;
p is the number of motor pole pairs. 100% corresponds
to the rated slip frequency of motor △f.

Low-frequency
oscillation control
factor of motor 1
Under SVPWM control mode, the motor, especially the
large-power motor may experience current oscillation
during certain frequencies, which may lead to unstable
motor operation, or even VFD overcurrent, users can
adjust these two parameters properly to eliminate such
phenomenon.
