f=fb-n*p/60
where fb is the rated frequency of motor 2,
corresponding to P12.02; n is the rated speed of
motor 2, corresponding to P12.03; p is the number of
pole pairs of motor 2. 100% corresponds to the rated
slip frequency
△
f of motor 2.
Setting range: 0.0–200.0%
P04.23
Low-frequency
oscillation control
factor of motor 2
In the SVPWM mode, current oscillation may easily
occur on motors, especially large-power motors, at
some frequency, which may cause unstable running
of motors or even overcurrent of inverters. You can
modify this parameter to prevent current oscillation.
Setting range of P04.23: 0–100
Setting range of P04.24: 0–100
Setting range of P04.25: 0.00 Hz–P00.03 (Max.
