P04.00 | Motor 1V/F curve setting | These function codes define the V/F curve of Goodrive300 motor 1 to meet the need of different loads. 0: Straight line V/F curve；applying to the constant torque load 1: Multi-dots V/F curve 2: 1.3th power low torque V/F curve 3: 1.7th power low torque V/F curve 4: 2.0th power low torque V/F curve Curves 2–4 apply to the torque loads such as fans and water pumps. Users can adjust according to the features of the loads to achieve a best energy-consuming effect. 5: Customized V/F(V/F separation); on this mode, V and F can be separated from adjusted through the frequency given channel set by P00.06 or the voltage given channel set by P04.27 to change the feature of the curve. Note: Vb in the below picture is the motor rated voltage and fb is the motor rated frequency.

P04.01 | Torque boost of motor 1 | Boost compensation can be given to the output voltage for compensating the features of low frequency torque. P04.01 is for the Max. Output voltage Vb. P04.02 defines the percentage of closing frequency of manual torque to fb. Torque boost can improve the features of low frequency torque of V/F. Torque boost should be selected according to the load. The bigger the load is, the bigger the boost is. Too big torque boost is inappropriate because the motor will run with over-magnetic, and the current of the VFD will increase to raise the temperature of the VFD and decrease the efficiency. When the torque boost is set to 0.0%, the VFD is automatic torque boost. Torque boost threshold: under the threshold, the torque boost is valid, but over the threshold, the torque boost is invalid.

Too high low frequency voltage will heat the motor excessively or cause damage. The VFD may stall when overcurrent or overcurrent protection.
