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:
-n*p/60
△f=f
b
Of which, f
1, corresponding to function code P02.02. n
is the rated rotating speed of motor 1,
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 frequencies, which may cause
unstable motor running, or even VFD
overcurrent. You can adjust the two
function codes properly to eliminate such
phenomenon.
