7.2.2 Friction system faults
The following faults of the friction system can occur when op-
erating the variable speed drive.
If the output shaft does not turn although the motor is running
or the specified torque is not transferred, the following may be
the causes:
•
The wear limit of the races is exceeded. In this case, re-
place the races.
•
The running surfaces of the friction system oily. Rectify
the cause of the oiling, clean the friction system and re-
place the races.
After a brief blockage of the output shaft, knocking sounds are
audible because a calotte has formed on the race surface.
Small calottes can recede. Replace the races for persistent
knocking sounds.
The replacement of the races is described in the document
with ID 440226.
