9.1.2.7 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 supplyundervoltage
♦ 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) ??
I 2 t motor monitor has responded
F037
(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
