Log
To see an overview of the emergency mode-related events, view the emergency mode log, parameter group 18-1* Emergency Mode Log,
or press [Alarm Log] on the LCP. The log includes up to 10 of the latest events. Warranty-affecting alarms have a higher priority than the
other 2 types of events.
The emergency mode alarm log can only be reset by a Danfoss authorized service partner. To secure the emergency mode operation
documentation, the 1st critical alarms can never be removed.
The following events are logged:
W200 - Emergency mode.
l
W201 - Emerg. M mode was act. (deactivated).
l
W202 - Emerg. M limits exceeded covered by the activated critical alarm number.
l
(W280) - Emcy M service warning - service is needed.
l
(W281) - Emcy OPR unexpected - emergency mode does not work as expected.
l
All alarms are logged as usual, and critical emergency mode alarms are logged in the emergency mode log in parameter group 18-1*
Emergency Mode Log.
During emergency-mode operation, all stop commands to the drive are ignored, including coast/coast inverse and external
interlock. The keypad is also locked during emergency mode to prevent user interference during operation of the safety system.
However, if Safe Torque Off is available in the drive, this function is still active.
Emergency mode has a special live zero function for handling lost analog signal inputs used for emergency mode setpoint/
feedback, for example, for handling a burnt cable. How emergency mode should continue in these live zero situations is
configured in parameter 6-02 Emergency Mode Live Zero Timeout Function. If live zero is activated, Emergency mode not working
as expected is activated so that a redundant system can take over or a setup change can be activated. A warning for live zero has a
higher priority than the warning Emergency mode and will replace that information in the display.
If setting the command [11] Start Reversing on a digital input terminal in parameter 5-10 Terminal 18 Digital Input, the drive
understands this as a reversing command.
