■ Control unit
On the front of the frequency converter there
is a control panel.
The control panel is div ided into four funct ion groups:
1. Six-digit LED display.
2. Keys for changing parameters and shifting
display function.
3. Indicator la mps.
4. Keys for local operation.
All displays of data are in the form o f 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 connect ion (ON),
warning (W A RNING) and alarm (ALARM ). Most of
the frequency converter’s parameter Setups can be
changed immediately v ia 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 parame ters
used for the Quick menu.
The[QUIC K MENU] key is also used if a change to
a parameter value is not to be implemented.
See also [QUICK M ENU] + [+].
[CHANGE DATA] is used for changing a setting.
The [CHANGE DATA] key is also used for confirming
a change of parameter settings.
[+] / [-] are u sed for selecting parameters and
for changing parameter va lues.
These keys are also used in Display mode for
selecting the display of an operat ing value.
The [QUICK MENU] + [+] keys must be
pressed at the same t ime 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 fl ash if the stop function is ac tivated.
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 co mmand.
■ Manual initialisation
Disconnect mains voltage. Hold the [QUICK
MENU] + [+] + [CHANGE D ATA] keys down while
simultaneously reconnecting the mains voltage.
Release the keys; the frequency converter has now
been programmed for the factory setting.
