Set F30 to 0 {Linear}.
This pattern maintains a linear Volts/frequency ratio from F23 - [Start frequency] to F22- [Base frequency]. This is appropriate for constant torque applications.
F22 – [Base frequency]: Inverter outputs its rated voltage at this level. Enter the motor nameplate frequency.
F23 – [Start frequency]: Inverter starts to output its voltage at this level.
