OVERHEATING AND DAMAGE TO THE MOTOR
Depending on the s ettings of this param eter, the error res pons e to detected errors is dis abled or the
trans ition to the operating s tate Fault is s uppres sed if an error is detected.
•
Verify that the s ettings of this param eter do not res ult in equipm ent dam age.
Failure to follow these instructions can result in equipment damage.
Behavior in the event of the drive overheating.
Note
: An error 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
[Fre e w heel] (YES) : Freew heel stop
[Per STT] (Stt) : Stop according to configuration of [Type of stop] (Stt) page 173 , 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 cont rol] (tCC) and [2 wire type] (tCt) page 125 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 s pd] (LFF) : Change to fallback speed, maintained as long as the detected fault persists and the run command has
not been removed (2)
[Spd m aint.]
(rLS) : The drive maintains the speed being applied w hen the detected fault occurred, as long as the detected
fault is present and the run command has not been removed (2)
[Ram p s top] (rMP) : Stop on ramp
[Fas t s top]
(FSt) : Fast stop
[DC inje ction] (dCI) : DC injection stop. This type of stop cannot be used w ith certain other functions. See table on page 163

Threshold for drive thermal alarm (logic output or relay).
(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.
These parameters only appear if the corresponding function has been selected in another menu. When the parameters can
also be accessed and adjusted from w ithin the configuration menu for the corresponding function, their description is detailed
in these menus, on the pages indicated, to aid programming.
Parameter that can be modified during operation or w hen stopped.
To change the assignment of this parameter, press the ENT key for 2 s.
