Description
△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%
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
VFDs. 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.
