VFD (inverter)

DANGER

•

Electric shock hazard!

High voltage inside electric panel. DO NOT touch bare

terminals and/or wires.

Figure 2: VFD control panel

NOTE 1:

VFD setup must be performed only when the

drive is stopped.

NOTE 2:

After setting parameter 02.00 to 9, VFD

displays End , and gets back to the main indication

mode. After this, continue setup process from parameter

00.03.

Parameters changing procedure

1. Locate the VFD control panel, see Fig 2.

2. To change or view parameter value, press

, the display shows 00.__

3. Press

or

to choose the first two digits of the parameter (for example, 02).

4. Press

again, display shows 02.00 .

5. Press

or

to choose the second two digits of the parameter, for example, 02.11 .

6. Press

again to see the current value of the parameter. Change value, if needed, with

or

.

7. Press

to confirm and save the new value, the display shows End .

8. Press

to return back to the previous level of selection or to the main mode.
