4.1.2 How to set extended parameters

The VF-A7 inverter has extended parameters to allow you to make full use of its functions. The code of every extended parameter is composed up of an  and a 3-digit number.

Extended parameter         

Press the Monitor key once, then press the ▲ or ▼ key to select a parameter (～ ) from among the basic parameters.

	～
ENT	～
	～
MON	～
	～
	～
	～
	～
	～

Select the parameter you want to change by pressing▲ and ▼ key, then press the Enter key to display the parameter setting.

：Press the Monitor key to switch to parameter setting mode. ( is displayed.)

：Select the parameter (～) the code of which is the closest to that of the parameter you want to change.

：Press the Enter key to activate the selected parameter.

：Select the parameter you want to change .

：Press the Enter key to display the extended parameter setting (value) you want to change.

：Change the extended parameter setting (set value).

：Press the Enter key to save the change.

You can return to the previous step by pressing the MON key instead of the ENT key.
