Configuration Mode (ConF)
Deferred stop on thermal alarm
This function helps to prevent the drive stopping between two s teps of the proces s if the drive or m otor
overheats, by authorizing operation until the next s top. At the next s top, the drive is locked until the therm al
state falls back to a value, which undershoots the s et thres hold by 20%. Exam ple: A thres hold set at 80%
enables reactivation at 60%.
One therm al s tate threshold m ust be defined for the drive, and one therm al s tate threshold for the m otor(s ),
which will trigger the deferred s top.

Thermal alarm stop function allow to set a custom alarm thermal level for the drive or the motor. When one of these levels is
reached, the drive trips in freewheel stop.
