Warranty-aecting alarms (see parameter 24-09 Fire Mode Alarm Handling)
•
Fire mode activated
•
Fire mode deactivated
All critical alarms occurring while re mode is activated are logged as usual.
NOTICE
During re mode-operation, all stop commands to the frequency converter are ignored, including coast/coast inverse
and external interlock. However, if Safe Torque O is available in the frequency converter, this function is still active.
NOTICE
If using the live zero-function in re mode, then it is also active for analog inputs other than that used for re mode
setpoint/feedback. Should the feedback to any of those other analog inputs be lost, for example a cable is burned, live
zero-function operates. If this is not wanted, disable the live zero-function for those other inputs.
Set the wanted live zero-function in case of a missing signal when re mode active in parameter 6-02 Fire Mode Live
Zero Timeout Function.
Warning for live zero has a higher priority than the warning Fire Mode.
NOTICE
If setting the command [11] Start Reversing on a digital input terminal in parameter 5-10 Terminal 18 Digital Input, the
frequency convertor understands this as a reversing command.
