Parameters
24-00 FM Function
Option: Function:
[4] Enabled- In this mode, the motor operates in a clockwise
Run direction. When receiving a reversing signal, the
Fwd/Rev motor operates in counterclockwise direction. If
parameter 24-01 Fire Mode Configuration is set
to [3] Closed Loop, the motor cannot operate in
counterclockwise direction.
24-01 Fire Mode Configuration
Select to use closed-loop or open-loop operations.
Option: Function:
[0] Open Loop
*
NOTICE
[3] Closed Loop
When set to [3] Closed Loop, the
commands Reversing and Start
Reversing do not reverse the direction
of the motor.
Motor speed is determined by a reference
from the built-in PI controller varying the
motor speed as of a closed-loop control
process (for example constant pressure or
flow). Configure the PI controller in parameter
group 20-8* PI Basic Setting and parameter
group 20-9* PI Controller.
24-05 FM Preset Reference
Range: Function:
0 % [-100 - 100 %] Enter the required preset reference/
*
setpoint as a percentage of the fire mode
maximum reference set in Hz.

[1] Analog Input 53
[2] Analog Input 54
[7] Pulse input 29
24-07 Fire Mode Feedback Source
This parameter defines which input on the frequency converter
should be treated as the source of the feedback signal.
Option:
[0] No function

[1] Analog Input 53
[2] Analog Input 54
[3] Pulse input 29

NOTICE
Certain alarms can affect the lifetime of the frequency
converter. If 1 of these ignored alarms occurs while in
fire mode, a log of the event is stored in the fire mode
log.
In fire mode log, the 10 latest events of alarms that
affect warranty, fire mode activation, and fire mode
deactivation are stored.
NOTICE
The setting in parameter 14-20 Reset Mode is disregarded
if fire mode is active (see parameter group 24-0* Fire
Mode).

Table 3.14 Fire Mode Alarm Handling
Function:
3.16.2 24-1* Drive Bypass
If a fire mode coast occurs (see parameter 24-00 FM
Function), the frequency converter includes a feature that
can automatically activate an external electro-mechanical
bypass.
The bypass switches the motor to operation directly on
line. One of the digital outputs or relays in the frequency
converter activates the external bypass, when programmed
02/2017 All rights reserved.
Function:
Trip+Reset, If this mode is selected, the frequency
Critical converter continues to run, ignoring most
Alarms alarms, even if doing so may damage the
frequency converter. Critical alarms are
alarms that cannot be suppressed but a
restart attempt is possible (infinity automatic
reset).
Trip, Critical In case of a critical alarm, the frequency
Alarms converter trips and does not auto-restart
(manual reset).
Trip, All It is possible to test the operation of fire
Alarms/Test mode, but all alarm states are activated
normally (manual reset).
