1.Select MENU (SOFT KEY 2). The Main menu will be displayed.

2.Use the UP or DOWN keys to highlight PAR BACKUP on the display screen and press ENTER (SOFT KEY 2).

3.Use the UP or DOWN keys to highlight UPLOAD TO PANEL and press SEL (SOFT KEY 2).

4.The text “Copying Parameters” will be displayed with a progress indicator. To stop the process, select ABORT (SOFT KEY 1).

5.When the upload is complete, the text “Parameter upload successful” will be displayed.

6.The display will then return to the PAR BACKUP menu. Select EXIT (SOFT KEY 1) to return to the main menu.

7.The control panel can now be disconnected from the drive.

Download All Parameters

To download all parameters from the control panel to the VFD, perform the following procedure:

1.Install the control panel with the correct parameters onto the VFD.

2.Select MENU (SOFT KEY 2). The Main menu will be displayed.

3.Use the UP or DOWN keys to highlight PAR BACKUP on the display screen and press ENTER (SOFT KEY 2).

4.Use the UP or DOWN keys to highlight DOWNLOAD TO DRIVE ALL and press SEL (SOFT KEY 2).

5.The text “Restoring Parameters” will be displayed with a progress indicator. To stop the process, select ABORT (SOFT KEY 1).

6.When the download is complete, the text “Parameter download successful” will be displayed.
