Fault Description
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)

10.1.2.7 Drive faults
F035 Drive is blocked
(active in operating states of – –, I, II)
This monitoring function responds if the following conditions are fulfilled for longer than the period set in parameter P355:
• Positive or negative torque or armature current limit
• The armature current is higher than 1% of the converter rated armature DC current
• The actual speed is less than 0.4% of maximum speed
Possible fault causes
• Drive is blocked
F036 No armature current is flowing
(active in operating states of – –, I, II)
This monitoring function responds if the armature firing angle is at the rectifier stability limit for more than 500 ms and the
armature current is less than 1% of the converter rated armature DC current.
Possible fault causes
• Armature circuit is open
(e.g. DC fuses have blown, open circuit, etc.)
• Rectifier stability limit α
G
(P150) is incorrectly set
• Drive is operating at α
G
limit (e.g. due to supply undervoltag)
• EMF is too high because maximum speed setting is too high,
refer to P083, P115, P143, P741)
• EMF is too high because field weakening is not selected (refer to P082)
• EMF is too high because field current is set too high (refer to P102)
• EMF is too high because transition speed for field weakening is set too high (refer to P101) ??
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 armature current.
Possible fault causes
• Parameter P114 is incorrectly set
• Drive has been operating for too long at >110% of rated motor armature 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 fault causes
• 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
