7.5 V/F control• Linear V/F pattern operationGroup Code Parameter Name Setting Range Initial UnitFunction group 1 F22 [Base frequency] - 30 ~ 400 60.00 HzF23 [Start frequency] - 0.1 ~ 10.0 0.50 HzF30 [V/F pattern] 0 0 ~ 2 0Function 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 nameplatefrequency. Start Frequency: Inverter starts to output its voltage at this level.Base freq.Freq.Start freq.Inverter ratedvoltageVoltageRuncommand• Square V/F patternGroup Code Parameter Name Setting Range Initial UnitFunctiongroup 1F30 [V/F pattern] 1 0 ~ 2 0• Set F30 to 1{Square}.• This pattern maintains squared volts/hertz ratio. Appropriate applications are fans, pumps,etc.100%VoltageBase freq.Freq.7-17
