The following table helps you with troubleshooting:
Problem
Possible cause
Solution
Drive turns in the
wrong direction
Incorrect phase
sequence
•
Swap 2 phases on the input power terminals
X105 and X106
Motor does not run,
no current con-
sumption
Missing line voltage
•
Check incoming cable, correct
•
Check line protection fuse, replace
No DC 24 V supply
•
Check DC 24 V supply, connect.
Missing "RUN" signal
•
Set "RUN" signal (pin X101:22 = 24 V).
Overtemperature error
•
Motor or power semiconductor too hot, let it
cool down, reduce load
•
TF not connected, check connections,
correct
Motor buzzes, high
current consump-
tion
Mechanical compo-
nents blocking
Defective winding
•
Correct mechanical fault
•
Replace drive
2-phase operation
•
Check fuses and line cable connections
•
Provide 3 phases
Brake does not release •
Carry out brake maintenance, see operating
instructions of the motor
Brake rectifier is defect •
Replace brake rectifier
