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.
NOTE
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 adjust-
able frequency drive is to start using the local refer-
ence (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 adjust-
able frequency drive is to remain stopped when the
mains voltage is engaged, until the [START]-key is ac-
tivated. 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 adjustable
frequency drive is to remain stopped when the mains
voltage is cut back in. Parameter 003
Local reference
is to be zeroed.
NOTE
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.
