Illustration 1.28 Display Mode
In normal operation, up to 4 different display data items
can optionally be shown continuously: 1,1, 1,2, 1,3 and 2.
The present operation status or alarms and warnings that
have been generated are displayed in line 2 in the form of
a number.
If alarms occur, this is displayed in lines 3 and 4 with
explanatory text.
A warning appears flashing in line 2 with explanatory text
in line 1. The active set-up also appears in the display.
The arrow indicates the selected direction of rotation. Here
the frequency converter shows that it has an active
reversing signal. The body of the arrow disappears if a stop
command is given, or if the output frequency drops below
0.1 Hz.
The bottom line displays the frequency transformer's
status. The scroll bar shows which operating values can be
displayed in lines 1 and 2 in Display mode. Use [+] or [-]
keys to make changes.

This topic describes the 4 display modes that the LCP
control unit supports.
Display Mode I
This Display mode is standard after start-up or initialisation.
50.0 Hz
FREQUENCY
MOTOR IS RUNNING
Illustration 1.29 Display Mode I
