NOTICE
Before adjusting the PID controller set
parameter 24-09 Fire Mode Alarm Handling,
[2] Trip, All Alarms/Test.
NOTICE
If [2] Enable-Run Reverse is selected in
parameter 24-00 Fire Mode Function, [3]
Closed Loop cannot be selected in
parameter 24-01 Fire Mode Configuration.
When fire mode is active, the motor runs with a
fixed speed based on a reference set. The unit is
the same as selected in parameter 0-02 Motor
Speed Unit.
When fire mode is active, the built-in PID
controller controls the speed based on the
setpoint and a feedback signal selected in
parameter 24-07 Fire Mode Feedback Source. Select
the unit in parameter 24-02 Fire Mode Unit. For
other PID controller settings use parameter group
20-** FC Closed Loop as for normal operation. 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.
Function:
Select the desired unit when fire mode is active
and running in closed loop.

FireModeUnit] parameter 24-05 Fire Mode Preset
Reference and value of signal on

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.
