Parameter Function
Note: 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 characteristic
Suitable for centrifugal fans / pumps
•
P1300 = 3: V/f with a programmable characteristic
User defined characteristic (see P1320)
•
P1300 = 4: V/f with linear characteristic and Economy Mode
Linear characteristic with Economy Mode
•
Modifies the output voltage to reduce power consumption
•
P1300 = 5,6: V/f for textile applications
Slip compensation disabled.
•
Imax controller modifies the output voltage only.
•
Imax controller does not influence the output frequency.
•
P1300 = 7: V/f with quadratic characteristic and Economy Mode
Quadratic characteristic with Economy Mode
•
Modifies the output voltage to reduce power consumption
•
P1300 = 19: V/f control with independent voltage setpoint
The following table presents an overview of control parameters (V/f) that can be modified in relationship to
P1300 dependencies:
