Parameter Descriptions
24-03 Fire Mode Min Reference
This parameter defines the minimum speed reference for the fire
mode to operate from, although the motor speed limits in
parameter 4-10 Motor Speed Direction has the highest priority and
limits are set. The value match the motor unit selection in
3 3
parameter 0-02 Motor Speed Unit.

24-04 Fire Mode Max Reference
This parameter defines the maximum speed reference which the
fire mode can operate to, although the motor limits in
parameter 4-10 Motor Speed Direction has the highest priority.
This maximum value is also used as reference value for the 8
preset values calculations in %.

24-05 Fire Mode Preset Reference
A parameter array with 8 elements (0-7). The 8 present values
(zones) are for open-loop control. Index [0] is used for basic fire
mode control. Indexes 1-7 are used to enhance fire mode
control, which also overwrites the basic control. Additional
reference value can be added via parameter group 24-**.

Function:
[ -999999.999 Minimum 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 fire
mode is active, the unit is selected
by the setting of
parameter 0-02 Motor Speed Unit.
For closed loop, select the unit in
parameter 24-02 Fire Mode Unit.
Function:
[ par. 24-03 - Maximum speed at which fire mode
operates. The value is used as %

Reference and value of signal on
input selected in
parameter 24-06 Fire Mode Reference
