Basic Functions
88
7.5 V/F control
Linear V/F pattern operation 7.5.1
Group Code Parameter Name Setting Range Default Unit
Function group 1
F22 [Base frequency] - 30 - 400 60.00 Hz
F23 [Start frequency] - 0.1 - 10.0 0.50 Hz
F30 [V/F pattern] 0 0 - 4 0
Function group 2 H40 [Control mode select] - 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.
►
Base Frequency: Inverter outputs its rated voltage at this level. Enter the motor
nameplate frequency.
►
Start Frequency: Inverter starts to output its voltage at this level.
Square V/F pattern 7.5.2
Group Code Parameter Name Setting Range Default Unit
Function group 1 F30 [V/F pattern] 1 0 - 4 0
Set F30 to 1{Square}.

This pattern maintains squared volts/hertz ratio. Appropriate applications are fans, pumps, etc.
