Default
Modify
of motor 2
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
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 △ f of
motor 2.
Setting range: 0.0–200.0%
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
running, or even VFD overcurrent. You can
adjust the two function codes properly to
eliminate such phenomenon.
P04.23 setting range: 0–100
P04.24 setting range: 0–100
P04.25 setting range: 0.00Hz–P00.03 (Max.
