Minimum value for the reference/set
point (limiting the sum of value in
par. 24-05 Fire Mode Preset Reference
and value of signal on input selected in
par. 24-06 Fire Mode Reference Source).
If running in Open loop when Fire Mode
is active, the unit is chosen by the
setting of par. 0-02 Motor Speed Unit.
For closed loop, the unit is selected in
par. 24-02 Fire Mode Unit .

Maximum value for the reference/set
point (limiting the sum of value in
par. 24-05 Fire Mode Preset Reference
and value of signal on input selected in
par. 24-06 Fire Mode Reference Source).
If running in Open loop when Fire Mode
is active, the unit is chosen by the

24-05 Fire Mode Preset Reference
Range: Function:
0.00 % * [-100.00 -
100.00 %]
Enter the required preset reference/set
point as a percentage of the Fire Mode
Max Reference set in par. 24-04 Fire Mode
Max Reference. The set value will be added
to the value represented by the signal on
the analog input selected in par. 24-06 Fire
Mode Reference Source.
24-06 Fire Mode Reference Source
Option: Function:
Select the external reference input to
be used for the Fire Mode. This signal
will be added to the value set in
par. 24-06 Fire Mode Reference Source.
