frequency of SM 1)
Setting range of P04.08: 0.0%–110.0% (of the
rated voltage of motor 1)
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
-n*p/60
b
Of which, f is the rated frequency of the motor,
b
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 motor 1.
Setting range: 0.0–200.0%
In space voltage vector control mode, the motor,
especially the large-power motor, may
experience current oscillation at certain
