(Refer to Pr. 73 Analog input selection.)Inputting 0 to 5VDC (or 0 to 10V, 0 to 20mA) provides themaximum output frequency at 5V (10V, 20mA) and makes inputand output proportional. Use Pr. 73 to switch from among input 0to 5VDC (initial setting), 0 to 10VDC, and 0 to 20mA.Set the voltage/current input switch in the ON position to selectcurrent input (0 to 20mA). *1Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides themaximum output frequency at 20mA makes input and outputproportional. This input signal is valid only when the AU signal ison (terminal 2 input is invalid).Use Pr. 267 to switch from among input 4 to 20mA (initial setting),0 to 5VDC, and 0 to 10VDC.Set the voltage/current input switch in the OFF position to selectvoltage input (0 to 5V/0 to 10V). *1Use Pr. 858 to switch terminal functions.10VDC±0.4VPermissible loadcurrent 10mA5.2VDC±0.2VPermissible loadcurrent 10mAVoltage input:Input resistance10kΩ ± 1kΩMaximumpermissible voltage20VDCCurrent input:Input resistance245Ω ± 5ΩMaximumpermissible current30mAVoltage/currentinput switchswitch142259259259259switch215FrequencysettingauxiliaryFrequencysettingcommonInputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal2 or 4 frequency setting signal.
