P04.09
V/F slip
compensation gain
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=fb-n*p/60
Of which, f
b
is the rated frequency of motor 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.

P04.10
Low-frequency
oscillation control
factor of motor 1
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.

V/F curve setting of
motor 2
This group of function code defines the V/F
curve of motor 2 to meet the needs of
different loads.
0: Straight-line V/F curve
1: Multi-point V/F curve
2: Torque-down V/F curve (power of 1.3)
3: Torque-down V/F curve (power of 1.7)
4: Torque-down V/F curve (power of 2.0)
5: Customized V/F curve (V/F separation)
