Function:
point as a percentage of the Fire Mode
Max Reference set in Hz.
Function:
If this mode is selected, the frequency
converter will continue 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).
In case of a critical alarm, the frequency
converter trips and does not auto-restart
(Manual Reset).
It is possible to test the operation of Fire
Mode, but all alarm states are activated
normally (Manual Reset).

4.16.2 24-1* Drive Bypass
The frequency converter includes a feature, which can be
used to automatically activate an external electro-
mechanical bypass in case of the event of a Fire Mode
Coast (see parameter 24-00 FM Function).
The bypass switches the motor to operation direct on line.
The external bypass is activated by means of one of the
digital outputs or relays in the frequency converter, 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 can be deactivated only by either removing the Fire
Mode command signal or the power 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
