Note:For the settings in the parameter list, no units can be converted from % into A (ampere)/ V (volt).
Conversion from % into A (ampere)/V (volt) can be made in monitor mode only.
An example of setting for changing the unit of volt/current displayed from % to A/V
Set H to or .
When the VF-nC1-2007P inverter (current rating: 4.0A) is operated under the rated load (full-load).

Note:This parameter is designed to display the value obtained by multiplying the output frequency
of the inverter by an integer. Even if the rotational speed of the motor fluctuates with load
conditions, the output frequency will always be displayed.
