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 parame-
ters cannot be made; however, it will still be possible
to make data changes via serial communication. Pa-
rameter 009-012
Display readout can be changed via
the control panel.
019
Operating mode at power-up, local op-
eration
(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 fre-
quency converter is to start using the local reference
(set in parameter 003
Local reference ) and the 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 fre-
quency 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 refer-
ence .
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 Lo-
cal/remote operation ) the start/stop state
at the time of mains connection will de-
pend on the external control signals. If
Pulse start [8] is selected in parameter 302
Digital input , the motor will remain stopped
after mains connection.
020 Hand operation
(HAND OPERATION)
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 con-
trolled by external signals whereas the frequency con-
verter in Hand mode is controlled via a local reference
directly from the control unit.
Description of choice:
If Not active [0] is selected in this parameter, the Hand
mode function will be inactive. If Active [1] is selected
you can switch between Auto- and Hand mode. For
further information, see the Control Unit section.
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 set-
up the user can select up to 20 parameters for the
Quick Menu key.
Description of choice:
If not active [0] is selected, the standard setup of the
Quick Menu key is active.
