V/F slip
compensation gain
of motor 2
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 foll
ows:
ᶭ
f=f
b
-n*p/60
Of which, f
b
is the rated frequency of the motor 2,
corresponding to function code
P12.02. n is the
rated rotating speed of the motor 2,
corresponding to function code
P12.03. p is the
number
of pole pairs of the motor. 100.0%
corresponds to the rated slip frequency
ᶭ f of
motor 2.

P04.23
Low-frequency
oscillation control
factor of motor 2
In space voltage vector control mode, the motor,
especially the large
-power motor, may
experience current oscillation at certain
frequencies, which may cause unstable motor
