[1.8 FAULT MANAGEMENT]
(FLt-)
Deferred stop on thermal alarm
This function can be used in intermittent applications, where it is desirable to avoid any stops for which no command has been given.
It prevents untimely stopping if the drive or motor overheats, by authorizing operation until the next stop for which a command is given.
At the next stop, the drive is locked until the thermal state falls back to a value which undershoots the set threshold by 20%. Example: A trip
threshold set at 80% enables reactivation at 60%.
One thermal state threshold must be defined for the drive, and one thermal state threshold for the motor(s), which will trip the deferred stop.

CAUTION
The drive and motor are no longer protected in the event of thermal alarm stops. This
invalidates the warranty.
Check that the possible consequences do not present any risk.
Failure to follow these instructions can result in equipment damage.
