Indicator lamps
At the bottom of the control panel are a red alarm lamp,
a yellow warning lamp and a green voltage indicator
lamp.
If certain threshold values are exceeded, the alarm
and/or warning lamp are activated, while a status or
alarm text is shown on the display.
NB!
The voltage indicator lamp is activated
when voltage is connected to the frequen-
cy converter.
Local control
[STOP/RESET] is used for stopping the motor con-
nected or for resetting the frequency converter after a
drop-out (trip). Can be set to active or inactive via pa-
rameter 014
Local stop
.
If stop is activated Display line 2 will flash.
NB!
If an external stop function is not selected
and the [STOP/RESET] key is set to in-
active, the motor can only be stopped by
disconnecting the voltage to the motor or
the frequency converter.
[JOG] changes the output frequency to a preset fre-
quency while the key is held down. Can be set to active
or inactive via parameter 015
Local jog
.
[FWD / REV] changes the direction of rotation of the
motor, which is indicated by means of the arrow on the
display. Can be set to active or inactive via parameter
016
Local reversing
. The [FWD/REV] key is only active
when parameter 002
Local/remote operation
is set to
Local control
.
[START] is used to start the frequency converter. Is
always active, but cannot override a stop command.
NB!
If the local control keys are set to inactive,
these will both become active when the
frequency converter is set to
Local con-
trol
and

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 warn-
ings that have been generated are displayed in line 2
in the form of a number.
In the event of alarms this is displayed in lines 3 and 4
with explanatory text.
A warning will appear flashing in line 2 with explanatory
text in line 1. The active Setup will also appear on the
display.
The arrow indicates the selected direction of rotation.
Here the frequency converter shows that it has an ac-
tive reversing signal. The body of the arrow will disap-
pear 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 scrollbar shows which operating values
can be displayed in lines 1 and 2 in Display mode.
Changes are made using the [+ / -] keys.
