■ Indicator lamps
At the bottom of the control panel are a red alarm
lamp, a yellow warning lamp and a green voltage in-
dicator 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 frequency con-
verter.
■ 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
parameter 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 inactive, the
motor can only be stopped by disconnecting the volt-
age 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 pa-
rameter 016 Local reversing. The [FWD/REV] key is
only active when parameter 002 Local/remote opera-
tion 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 fre-
quency converter is set to Local control and Remote
control via parameter 002 Local/remote operation,
with the exception of [FWD/REV], which is only ac-
tive in Local control.
