DANGER
LOSS OF PERSONNEL AND EQUIPMENT PROTECTION
Enabling [Fault inhibit assign.] (InH) will disable the drive controller protection features.
• [Fault inhibit assign.] (InH) should not be enabled for typical applications of this equipment.
• [Fault inhibit assign.] (InH) should be enabled only in extraordinary situations where a thorough risk
analysis demonstrates that the presence of adjustable speed drive protection poses a greater risk than
personnel injury or equipment damage.
Failure to follow these instructions will result in death or serious injury.
If the assigned input or bit is at 0, detected fault monitoring is active. If the assigned input or bit is at 1, fault monitoring is inactive.
Active detected faults are cleared on a rising edge (change from 0 to 1) of the assigned input or bit.
Note: The Safe Torque Off function and any detected faults that help to prevent any form of operation are not affected by this
function.
Following faults can be inhibited:
AnF, CnF, COF, CrF1, dLF, EnF, EPF1, EPF2, FCF2, InFA, InFb, LFF3, ObF, OHF, OLC,
OLF, OPF1, OPF2, OSF, OtFL,PHF, PtFL, SLF1, SLF2, SLF3, SOF, SPF, SSF, tJF, tnF and
ULF.

WARNING
LOSS OF CONTROL
If Network fault management [Network fault mgt] (CLL) is set to [Ignore] (nO), communication control
will be inhibited.
For safety reasons, inhibiting the communication interruption detection should be restricted to the debug
phase or to special applications.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Behavior of the drive in the event of a communication interruption with a communication card.
[Ignore] (nO): Detected fault ignored
[Freewheel] (YES): Freewheel stop
[Per STT] (Stt): Stop according to configuration of [Type of stop] (Stt) page 158
, without fault tripping. In this case, the
fault relay does not open and the drive is ready to restart as soon as the detected fault disappears, according to the restart
conditions of the active command channel (for example, according to [2/3 wire control] (tCC) and [2 wire type] (tCt) page
112 if control is via the terminals). Configuring an alarm for this detected fault is recommended (assigned to a logic output, for
example) in order to indicate the cause of the stop
[Fallback spd] (LFF): Change to fallback speed, maintained as long as the detected fault persists and the run command has
not been removed (1)
[Spd maint.] (rLS): The drive maintains the speed being applied when the detected fault occurred, as long as the detected
fault is present and the run command has not been removed (1)
[Ramp stop] (rMP): Stop on ramp
[Fast stop] (FSt): Fast stop
[DC injection] (dCI): DC injection stop. This type of stop cannot be used with certain other functions. See table on page 148
