6 How to Program

6.1  Programming with MCT 10 Set-up

Software

The frequency converter can be programmed from the LCP,
or from a PC via the RS485 COM port by installing the MCT
10 Set-up Software. Refer to 

chapter 1.5 Additional

Resources

 for more details about the software.

6.2  Local Control Panel (LCP)

The LCP is divided into 4 functional sections.

Illustration 6.1 Local Control Panel (LCP)

A. Display

The LCD-display is illuminated with 2 alphanumeric lines.
All data is displayed on the LCP.

Illustration 6.1

 describes the information that can be read

from the display.

1

Parameter number and name.

2

Parameter value.

3

Set-up number shows the active set-up and the edit set-
up. If the same set-up acts as both active and edit set-up,
only that set-up number is shown (factory setting). When
active and edit set-up differ, both numbers are shown in
the display (set-up 12). The number flashing, indicates the
edit set-up.

4

Motor direction is shown to the bottom left of the display
– indicated by a small arrow pointing either clockwise or
counterclockwise.
