Parameters described in this page can be accessed by:
(1) The parameter can also be accessed in the [SETTINGS] (SEt-) menu.
(2) Because, in this case, the detected fault does not trigger a stop, it is recommended to assign a relay or logic output to
its indication.
FLt- [FAULT MANAGEMENT] (continued)
OHL- [DRIVE OVERHEAT]
OHL [Overtemp fault mgt]
[Freewheel] (YES)
CAUTION
RISK OF EQUIPMENT DAMAGE
Inhibiting drive overheating fault detection results in the drive not being protected. This invalidates the
warranty.
Check that the possible consequences do not present any risk.
Failure to follow these instructions can result in injury or equipment damage.

Behavior in the event of the drive overheating.
Note: A trip will occur when the thermal state reaches 118% of the rated state and reactivation will occur when the state falls
back below 90%.
[Ignore] (nO): Detected fault ignored
[Freewheel] (YES): Freewheel stop
[Per STT] (Stt): Stop according to configuration of [Type of stop] (Stt) page 158
, without 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 (2)
[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 (2)
[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
tHA [Drv therm. state al]
0 to 118% 100%
T
Trip threshold for drive thermal alarm (logic output or relay).

These parameters only appear if the corresponding function has been selected in another menu. When the parameters can
also be accessed and adjusted from within the configuration menu for the corresponding function, their description is detailed
in these menus, on the pages indicated, to aid programming.
T
Parameter that can be modified during operation or when stopped.
To change the assignment of this parameter, press the ENT key for 2 s.
