Ifthe ‘V2’ signal is affected by noise causing unstableoperation of the inverter, increase this value. Increasingthis value may make response time slower.EXT-05: V2 Mode Selection – Sub-A, Sub-CEXT► V2 volt x107 0.00 V070.00EXT► V2 mode05 None05Factory Default: None 00Factory Default: 0.00 V 0.00This is the minimum voltage of the ‘V2’ input at which theinverter outputs minimum frequency.‘V2’ signal can be used as the frequency reference andoverride function.EXT► V2 volt y108 0.00 Hz080.00[None]V2 signal is not used.[Override]‘V2’ signal override the frequency reference signal (V1, I,V1+I) selected in DRV-04.[Reference]‘V2’ signal is used as the frequency reference. At thistime, the frequency reference selected in DRV-04 isignored.EXT-06 ~ EXT-10: Analog Voltage Input (V2)Signal Adjustment – Sub-A, Sub-CThis is used to adjust the analog voltage input signalwhen the frequency is referenced or overridden by the‘V2’ control terminal. This function is applied when EXT-05 is set to ‘Override’ or ‘Reference’. ReferenceFrequency versus Analog Voltage Input Curve can bemade by four parameters of EXT-07 ~ EXT-10.Factory Default: 0.00 Hz 0.00This is the minimum frequency the inverter outputs whenthere is the minimum voltage (EXT-07) on the ‘V2’terminal.EXT► V2 volt x209 0.00 V 09 10.00Factory Default: 10.00 V 10.00This is the maximum voltage of the ‘V2’ input at whichthe inverter outputs maximum frequency.EXT► V2 volt y210 60.00 Hz 1060.00Factory Default: 60.00 Hz 60.00This is the maximum frequency the inverter outputswhen there is the maximum voltage (EXT-09) on the ‘V2’terminal.137
