trol 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 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 stop-
ped after mains connection.
