Modify
the mechanical characteristics of the motor. You
need to calculate the rated slip frequency of the
motor as follows:
△f=fb-n×p/60
where fb is the rated frequency of motor 1,
corresponding to P02.02; n is the rated speed of
motor 1, corresponding to P02.03; p is the number
of pole pairs of motor 1. 100% corresponds to the
rated slip frequency △f of motor 1.
Setting range: 0.0–200.0%
P04.10
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.
Setting range of P04.10: 0–100
Setting range of P04.11: 0–100
