Control unit
On the front of the frequency converter there is a con-
trol 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 supple-
ment to the display, there are three indicator lamps for
indication of mains connection (ON), warning (WARN-
ING) and alarm (ALARM). Most of the frequency con-
verter's parameter Setups can be changed immedi-
ately 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 pa-
rameter 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 ac-
tive [0] in parameter 014 Local stop/re-
set,and there is no stop command via the
digital inputs or serial communication, the
motor can only be stopped by disconnect-
ing the mains voltage to the frequency
converter.
[START] is used for starting the frequency converter.
It is always active, but the [START] key cannot over-
ride a stop command.
Manual initialisation
Disconnect mains voltage. Hold the [QUICK MENU] +
[+] + [CHANGE DATA] keys down while simultane-
ously reconnecting the mains voltage. Release the
keys; the frequency converter has now been program-
med for the factory setting.
