Description
voltage of motor 2)
Setting range of P04.18: P04.16–P04.20
Setting range of P04.19: 0.0%–110.0% (rated
voltage of motor 2)
Setting range of P04.20: P04.18–P12.02 (rated
frequency of asynchronous motor 2) or P04.18–
P12.16 (rated frequency of synchronous motor 2)
Setting range of P04.21:0.0%–110.0%(rated
voltage of motor 2)
This parameter is used to compensate for the
motor rotating speed change caused by load
change in the SVPWM mode, and thus improve
the rigidity of 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 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.
output frequency)
0: No action
1: Automatic energy-saving operation
Under light-load state, the motor can adjust the
output voltage automatically to achieve
energy-saving purpose
0: Keypad; output voltage is determined by P04.28
