Detailed parameter description
voltage of motor 1)
Setting range of P04.07: P04.05–P02.02 (rated
frequency of motor 1) or P04.05– P02.16 (rated
frequency of motor 1)
Setting range of P04.08: 0.0%–110.0% (rated
voltage of motor 1)
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.
Setting range: 0.0–200.0%
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 inverter
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
Setting range of P04.12: 0.00Hz–P00.03 (max.
output frequency)
