FireModeUnit]
Maximum value for the reference/
setpoint (limiting the sum of value in
parameter 24-05 Fire Mode Preset
Reference
and value of signal on input
selected in
).
If running in open loop when fire
mode is active, the unit is selected by
the setting
. For closed loop, select the unit in
parameter 24-02 Fire Mode Unit
.

The set value is added to the value represented
by the signal on the analog input selected in
parameter 24-06 Fire Mode Reference Source

Option:
Function:
Select the external reference input to
be used for the fire mode. This signal

Option:
Function:
Select the feedback input to be used
for the fire mode feedback signal
when fire mode is active.
If the motor also is controlled by the
built–in PID controller when in
normal operation, the same
transmitter can be used for both
cases by selecting the same source.

24-09 Fire Mode Alarm Handling
Option:
Function:
[0]
Trip+Reset,
Critical
Alarms
If this mode is selected, the frequency
converter continues to run, ignoring most
alarms, even if doing so may result in
damage of the frequency converter. Critical
alarms are alarms, which cannot be
suppressed but a restart attempt is possible
(infinity automatic reset).
[1]
*
Trip, Critical
Alarms
In case of a critical alarm, the frequency
converter trips and does not auto-restart
(manual reset).
[2]
Trip, All
Alarms/Test
It is possible to test the operation of fire
mode, but all alarm states are activated
normally (manual reset).
NOTICE
Warranty-affecting alarms. Certain alarms can affect the
lifetime of the frequency converter. Should 1 of these
ignored alarms occur while in fire mode, a log of the
event is stored in the fire mode-log.
Here the 10 latest events of warranty-affecting alarms,
fire mode activation, and fire mode deactivation are
stored.
NOTICE
The setting in
is disregarded
if fire mode is active (see parameter group
24-0* Fire
Mode
).
