Function:
In this mode, the motor operates in a clockwise
direction. When receiving a reversing signal, the
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.
Function:
point as a percentage of the fire mode
maximum reference set in Hz.
Function:
NOTICE
Warranty-affecting alarms. 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.
The fire mode log stores the 10 latest
events of warranty-affecting alarms, fire
mode activation, and fire mode deacti-
vation.
NOTICE
The setting in parameter 14-20 Reset
Mode is disregarded when fire mode is
active (see parameter group 24-0*, Fire
Mode).
If this mode is selected, the frequency
converter continues to run, ignoring most
alarms, even if doing so may result in damage
to the frequency converter. Critical alarms are
alarms, which cannot be suppressed but a
restart attempt is possible (Infinity Automatic
Reset).
If there is a critical alarm, the frequency
converter trips and does not autorestart
(manual reset).
It is possible to test the operation of fire
mode, but all alarm states are activated
normally (manual reset).

Table 4.16 Fire Mode Alarms
4.17.2 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
in parameter group 5-3* Digital Outputs or parameter
group 5-4* Relays.
NOTICE
The drive bypass cannot be deactivated if in fire mode. It
is deactivated only by either removing the fire mode
command signal or the supply to the frequency
converter.
When the drive bypass function is activated, the display on
the LCP shows the status message Drive Bypass. This
message has a higher priority than the fire mode status
messages. When the automatic drive bypass function is
enabled, it cuts in the external bypass according to
Illustration 4.24.
