ion gain of
motor 1
The function code is 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
b
-n*p/60
Of which, f
b
is the rated frequency of the
motor, 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.
