9.5 V/F control

Linear V/F pattern operation
Group Code Parameter Name Setting Range Initial Unit
Function group 1 F22
[Base frequency]
- 30 ~ 400 50.00 Hz
F23 [Start frequency] - 0.1 ~ 10.0 0.50 Hz
F30 [V/F pattern] 0
0 ~ 2 0
Function group 2 H40 [Control mode select] - 0 ~ 3 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.



Set F30 to 1{Square}.

This pattern maintains squared volts/hertz ratio. Appropriate applications are fans, pumps,
etc.
