FCD Series
Programming, FCD
300
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
still be possible to make data changes via serial
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.
020 Lock for Hand mode
(LOCK HAND MODE)
Value:
✭Not active (DISABLE)
[0]
Active (ENABLE)
[1]
Function:
In this parameter you can select whether it should
be possible or not to switch between Auto- and
Hand mode. In Auto mode the frequency converter is
controlled by external signals whereas the frequency
converter in Hand mode is controlled via a local
reference directly from the control unit.
Description of choice:
If Not a ctive [0] is selected in this parameter, the Hand
mode function will be inactive. This blocking can be
activated as desired. If Active [1] is selected you can
switch between Auto- and Hand mode.
NB!:

024 Userdefined Quick Menu
(USER QUICKMENU)
Value:
✭Not active (DISABLE)
[0]
Active (ENABLE)
[1]
Function:
In this parameter you can select the standard
setup of the Quick menu key on the control
panel and the LCP 2 control panel.
Using this function, in parameter 025 Quick Menu
setup the user can select up to 20 parameters
for the Quick Menu key.
Description of choice:
If not act ive [0] is selected, the standard setup
of the Quick Menu key is active.
If Active [1] is selected, the user-defined
Quick Menu is active.
✭ = factory setting. () = display text [] = value for use in communication via serial communication port
