• Function

These parameters are used to change the unit displayed on the display panel. % ⇔ A (ampere)/V (volt)

Frequency ⇔ Motor speed or load speed

■Parameter setting

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).

1) Displayed in percentage			2) Displayed in amperes/volts
		Output current:
	E			E 	Output current:
		100%			4.0A
		DC voltage:			DC voltage: 200V
	[			[	(converted into AC

*Conversion from % into A (ampere)/V (volt) can be made in status monitor mode only. For the settings in the parameter list, no units can be converted from % into A (ampere)/V (volt).

■An example of setting for displaying the motor or load speed

Set H to  or .

The value obtained by multiplying the operation frequency by the value set with H will be displayed, as shown below.

Value displayed = Frequency displayed or parameter-set frequency ⋅ Value set with H

1)Displaying the rotational speed of the motor

To switch from frequency (default: 60Hz) to speed (rotational speed of the 4P motor operated: 1800 (min-1)





H= H= 60⋅30.00=1800

2)Displaying the speed of the load

To switch from frequency (default: 60Hz) to speed (speed of the conveyer operated: 6m/min-1)



H=

.

H= 60⋅0.10=6.0

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.

* Using H, the following parameters can be converted.

• A display	Display of the monitored current
• V display	Display of the monitored voltage
• Free unit	Display of the monitored frequency
