■
Control unit
On the front of the frequency converter there
is a control panel.
The control panel is divided into four function groups:
1. Six-digit LED display.
2. Keys for changing parameters and shifting
display function.
3. Indicator lamps.
4. Keys for local operation.
All displays of data are in the form of a six-digit LED
display capable of showing one item of operating
data continuously during normal operation. As a
supplement to the display, there are three indicator
lamps for indication of mains connection (ON),
warning (WARNING) and alarm (ALARM). Most of
the frequency converter ’ s parameter Setups can be
changed immediately via the control panel, unless
this function has been programmed as Locked [1]
via parameter 018 Lock for data changes .

Control keys
[QUICK MENU] allows access to the parameters
used for the Quick menu.
The[QUICK MENU] key is also used if a change to
a parameter value is not to be implemented.
See also [QUICK MENU] + [+].
[CHANGE DATA] is used for changing a setting.
The [CHANGE DATA] key is also used for confirming
a change of parameter settings.
[+] / [-] are used for selecting parameters and
for changing parameter values.
These keys are also used in Display mode for
selecting the display of an operating value.
The [QUICK MENU] + [+] keys must be
pressed at the same time to give access to all
parameters. See Menu mode.
[STOP/RESET] is used for stopping the
connected motor or for resetting the frequency
converter after a trip.
Can be selected as Active [1] or Not active [0] via
parameter 014 Local stop/reset . In Display mode, the
display will flash if the stop function is activated.
NB!:
If the [STOP/RESET] key is set at Not active
[0] in parameter 014 Local stop/reset, and
there is no stop command via the digital
inputs or serial communication, the motor can
only be stopped by disconnecting the mains
voltage to the frequency converter.
[START] is used for starting the frequency
converter. It is always active, but the [START] key
cannot override a stop command.
■
Manual initialisation
Disconnect mains voltage. Hold the [QUICK
MENU] + [+] + [CHANGE DATA] keys down while
simultaneously reconnecting the mains voltage.
Release the keys; the frequency converter has now
been programmed for the factory setting.
