24-03 Fire Mode Min Reference
Range: Function:
Size

[ -999999.999 -
par. 24-04
FireModeUnit]
Minimum value for the
reference/set point (limiting the
sum of value in 24-05 Fire Mode
Preset Reference and value of
signal on input selected in
24-06 Fire Mode Reference Source).
If running in Open loop when Fire
Mode is active, the unit is chosen
by the setting of 0-02 Motor Speed
Unit. For closed loop, the unit is
selected in 24-02 Fire Mode Unit .

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

24-07 Fire Mode Feedback Source
Option: Function:
Select the feed back input to be
used for the Fire Mode feed back
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.
