24-01 Fire Mode Conguration
Option: Function:
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
Conguration.
The re mode can be controlled in
open loop with up to 8 dierent
preset values (zones), or in close
loop by an reference and feedback
signal. The reference and feedback
signal can come via drive input
signals or over the
eldbus.
[0] * Open Loop When re mode is active, the motor
runs with a xed speed based on a
reference set. The unit is the same
as selected in parameter 0-02 Motor
Speed Unit.
[3] Closed Loop When re 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
PID controller settings use
parameter group 20-** FC Closed
Loop as for normal operation. The
same PID conguration can be
selected for both normal, and re
mode, and the operation can be
continued as setup 1 to 4.
24-02 Fire Mode Unit
Option: Function:
By default, re mode is congured
for open-loop control where only
the motor unit is selected in
parameter 0-02 Motor Speed Unit.
For closed-loop operation, select
any of the following options.
