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
Of which, f is the rated frequency of the motor
b
1, corresponding to function code P02.02. n is
the rated rotating speed of the motor 1,
corresponding to the function code P02.03. p is
the number of pole pairs of the motor. 100.0%
corresponds to the rated slip frequency △f of
motor 1.
Setting range: 0.0–200.0%
In space voltage vector control mode, the
motor, especially the large-power motor, may
experience current
frequencies, which may cause unstable motor
running, or even VFD overcurrent. You can
