Possible Settings:
0 V/f with linear characteristic
1 V/f with FCC
2 V/f with parabolic characteristic
3 V/f with programmable characteristic
Note:
V/f mode:
P1300 = 1 : V/f with FCC (flux current control)
* Maintains motor flux current for improved efficiency.
* If FCC is chosen, linear V/f is active at low frequencies.
P1300 = 2 : V/f with a quadratic curve
* Suitable for centrifugal fans / pumps
The following table presents an overview of control parameters (V/f) that can be modify in relationship to
