F22 [Base frequency] - 30/400 60.0 Hz
F23 [Start frequency] - 0.1/10.0 0.5 Hz
F30 [V/F pattern] 0 0/2 0
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.
