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)
