Description
rated voltage 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=f
-n*p/60
b
Of which, f is the rated frequency of the motor,
b
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 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.

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)
