018 Lock for data changes
(DATA CHANGE LOCK)
Value:
Not locked (NOT LOCKED)
Locked (LOCKED)
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.
Operating mode at power-up, local op-
019
eration
(POWER UP ACTION)
Value:
Auto restart, use saved reference
(AUTO RESTART)
Forced stop, use saved reference
(LOCAL=STOP)
Forced stop, set ref. to 0
(LOCAL=STOP, REF=0)
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.
