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
.
