Used to compensate for the motor rotating speed
change caused by load change in the space
voltage vector 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=f
gain of motor 1 Of which, f
corresponding to function code P02.02. n is the
rated rotating speed of the motor, corresponding
to function code P02.03. p is the number of pole
pairs of the motor. 100.0% corresponds to the
rated slip frequency △ f of the motor.
Setting range: 0.0–200.0%
Low-frequency In space voltage vector control mode, the motor,
especially the large-power motor, may
of motor 1 experience current oscillation at certain
frequencies, which may cause unstable motor
High-frequency
running, or even inverter unit overcurrent. You
can adjust the two function parameters properly
of motor 1
to eliminate such phenomenon.
