24-03 Fire Mode Min Reference
Range: Function:
0 * [-999999.999 to +999999.999]
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 .
24-04 Fire Mode Max Reference
Range: Function:
1500 * [-999999.999 to
+999999.999]
Maximum value for the reference/set point (limiting the sum of value in
par. 24-05, Fire Mode Preset Refer-
ence
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 .
24-05 Fire Mode Preset Reference
Range: Function:
0% * [-100% to +100%]
Enter the required preset reference/set point as a percentage of the Fire Mode Max Reference set in par. 24-04.
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. 24-05, Fire Mode Preset Reference .

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.
