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 acti v ated, while a status
or alarm text is shown on the display.
NB!:
The voltage indicator lamp is acti v ated when
voltage is connected to the frequency converter.
Local control
[STOP/RESET] is used for stopping the motor
connected or for resetting the frequency converter
after a drop-out (trip). Can be set to acti v e or
inacti v e via parameter 014 Local stop.
If stop is acti v ated Display line 2 will flash.
NB!:
If an external stop function is not selected and
the [STOP/RESET] key is set to inacti v e, 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
frequency while the key is held down. Can be set to
acti v e or inacti v e 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 acti v e or inacti v e via
parameter 016 Local reversing. The [FWD/REV] key
is only acti v e when parameter 002 Local/remote
operation is set to Local control.
[START] is used to start the frequency converter. Is
always acti v e, but cannot override a stop command.

NB!:
If the local control keys are set to inacti v e,
these will both become acti v e when the
frequency converter is set to Local control
and Remote control via parameter 002 Local/remote
operation, with the exception of [FWD/REV], which
is only acti v e in Local control.

STATUS
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.
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 acti v e Setup
will also appear on the display.
The arrow indicates the selected direction of rotation.
Here the frequency converter shows that it has
an acti v e reversing signal. The body of the arrow
will disappear if a stop command is gi v en, 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.
