Cause : I2t power section monitor has responded (active in operating states of – –, I, II)
This monitoring function responds if the calculated I2t value of the power section reaches the permissible value for the power section concerned (see also P075).
Possible fault causes
♦ Drive has been operating at overload for too long
♦ Parameter P075 is incorrectly set
♦ Parameter P077 is incorrectly set
