P04 Group--V/F Control - INVT Goodrive3000 Series Operation Manual

Goodrive3000 series medium voltage VFD
P03.26: It is used when the AM is in flux-weakening control. The running performance of the motor can be improved by
adjusting the parameters properly.
P03.24–P03.26 are invalid to vector control mode 1 and V/F control.

code
V/F curve setting of
P04.00
The function code defines the V/F curve of motor 1 to meet the needs of different loads.
0: Straight-line V/F curve, applicable to constant torque loads
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)
Curves 2 – 4 are applicable to the torque loads such as fans and water pumps. You can adjust according to the
characteristics of the loads to achieve best performance.
5: Customized V/F (V/F separation); in this mode, V can be separated from F and F can be adjusted through the
frequency setting channel set by P00.06 or the voltage setting channel set by P04.27 to change the characteristics of the
curve.
