2800 Series
Description of choice:
If Not active [0] is selected in this parameter,
the [JOG]-key will be inactive.
016 Local reversing
(LOCAL REVERSING)
Value:
✭Not active (DISABLE)
[0]
Active (ENABLE)
[1]
Function:
In this parameter you can select/deselect the reversing
function on the LCP control panel. The key can only
be used if parameter 002 Local/remote operation
is set to Local operation [1] and parameter 013
Localcontrol to Local control, open loop [1] or
Local control as parameter 100 [3].
Description of choice:
If Disable [0] is selected in this parameter, the
[FWD/REV] key will be disabled. See also parameter
200 Output frequency range.
017 Local reset of trip
(LOCAL RESET)
Value:
Not active (DISABLE)
[0]
✭Active (ENABLE)
[1]
Function:
In this parameter, the reset function on the control
panel can be engaged/disengaged.
Description of choice:
If Not active [0] is selected in this parameter,
the reset function will be inactive.
NB!:
Select Not active [0], only if an external reset
signal has been connected via the digital inputs.
018 Lock for data changes
(DATA CHANGE LOCK)
Value:
✭Not locked (NOT LOCKED)
[0]
Locked (LOCKED)
[1]
Function:
In this parameter, it is possible to ’lock’ the controls
to disable data changes via the control keys.
Description of choice:
If Locked [1] is selected, data changes in the
parameters cannot be made; however, it will
stillbepossibletomakedatachangesviaserial
communication. Parameter 009-012 Display readout
can be changed via the control panel.
019 Operating mode at power-up, local
operation
(POWER UP ACTION)
Value:
Auto restart, use saved reference
(AUTO RESTART)
[0]
✭Forced stop, use saved reference
(LOCAL=STOP)
[1]
Forced stop, set ref. to 0
(LOCAL=STOP, REF=0)
[2]
Function:
Setting of the required operating mode when the
mains voltage is engaged. This function can only
be active if Local operation [1] has been selected
in parameter 002 Local/remote operation.
Description of choice:
Auto restart, use saved ref. [0] is selected if the
frequency converter is to start using the local reference
(set in parameter 003 Local reference)andthe
start/stop state given via the control keys immediately
prior to the mains voltage being cut out.
Forced stop, use saved ref. [1] is selected if the
frequency converter is to remain stopped when the
mains voltage is engaged, until the [START]-key
is activated. After a start command the motor
speed is ramped up to the saved reference in
parameter 003 Local reference.
Forced stop, set ref. to 0 [2] is selected if the
frequency converter is to remain stopped when
the mains voltage is cut back in. Parameter 003
Local reference is to be zeroed.
NB!:
In remote operation (parameter 002
Local/remote operation) the start/stop state
at the time of mains connection will depend
on the external control signals. If Pulse start [8] is
selected in parameter 302 Digital input,themotor
will remain stopped after mains connection.
