24-04 Fire Mode Max Reference
Range: Function:
Size
related*
[ par. 24-03 -
999999.999
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 parameter 24-06 Fire Mode
Reference Source).
If running in open loop when re
mode is active, the unit is selected by
the setting parameter 0-02 Motor Speed
Unit. For closed loop, select the unit in
parameter 24-02 Fire Mode Unit.
24-05 Fire Mode Preset Reference
Range: Function:
0 %* [-100 -
100 %]
Enter the required preset reference/set point as
a percentage of the Fire Mode Max Reference
set in parameter 24-04 Fire Mode Max Reference.
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.
24-06 Fire Mode Reference Source
Option: Function:
Select the external reference input to
be used for the re mode. This signal
is added to the value set in
parameter 24-06 Fire Mode Reference
Source.

Option: Function:
Select the feedback input to be used
for the re mode feedback signal
when re 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
(innity 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 re
mode, but all alarm states are activated
normally (manual reset).
NOTICE
Warranty-aecting alarms. Certain alarms can aect the
lifetime of the frequency converter. Should 1 of these
ignored alarms occur while in re mode, a log of the
event is stored in the re mode-log.
Here the 10 latest events of warranty-aecting alarms,
re mode activation, and re mode deactivation are
stored.
NOTICE
The setting in parameter 14-20 Reset Mode is disregarded
if re mode is active (see parameter group 24-0* Fire
Mode).
