Cause : Line frequency greater than the maximum line frequency acc. to parameter P364 comes when frequency of armature supply is greater then maximum line frequency.
- Up to software version 1.7 the threshold for activation of the fault message (maximum line frequency) is 65Hz
- Frequency of the armature supply > maximum line frequency
- Frequency of the field supply > maximum line frequency
- Line frequency greater than the maximum line frequency for longer than set in parameter P086 (if >0)

Cause : Line frequency greater than the maximum line frequency acc. to parameter P364 (active in operating states of ≤ o5)
1 Frequency of the armature supply > maximum line frequency
2 Frequency of the field supply > maximum line frequency
4 Line frequency greater than the maximum line frequency for longer than set in parameter P086 (if >0)
