Fault Description
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Further information (r047.002 to r047.016)
10.1.2.6 External faults

10.1.2.7 Drive faults
F035 Drive blocked
(active in operating states of – –, I, II)
The monitoring function responds if the following conditions are fulfilled for longer than the time set in parameter P355:
• Positive or negative current limit reached
• Stator current is greater than 1% of converter rated DC current
• The actual speed value is less than 0.4% of maximum speed
Possible causes of fault
• Drive blocked
F036 No stator current can flow
(active in operating states of – –, I, II)
This monitoring function responds if the firing angle is at 0° for more than 500 ms and the stator current is less than 1% of the
converter rated DC current.
Possible causes of fault
• Break in motor cable
F037 I
2
t motor monitor has responded
(active in operating states of – –, I, II)
This monitoring function responds when an I
2
t value is reached which corresponds to the final temperature at 110% of the rated
motor current.
Possible causes of fault
• Parameter P114 is incorrectly set
• Drive has been operating for too long at >110% of rated motor current
F038 Overspeed
(active in operating states of – –, I, II)
This fault message is activated if the actual speed value (selected in P595) exceeds the positive (P380) or negative (P381)
threshold by 0.5%.
Possible causes of fault
• Lower current limit has been input
• Current-controlled operation
• P512, P513 are set too low
• Tachometer cable contact fault in operation close to maximum speed
