Change of the system's natural frequency
due to a broken spring
Undo screws of the spring assemblies, check springs,
replace broken or damaged springs. CAUTION!
Cause for a broken spring is often too high oscillation
amplitude. --> Check oscillation amplitude!
The drive is improperly adjusted, i.e. the
system's natural frequency does not
match the exciting frequency
Adjust the drive by changing the spring stiffness, the
position of the adjustment plates or by setting the os-
cillation frequency with the controller. Tighten the
screws of the spring assemblies. CAUTION! Adjust
the conveyors according to the operating manual!
Conveyor rail lifts off or hits
Cause of fault
Fault repair
The conveyor rail is not sufficiently fas-
tened to the corresponding drive
Tighten fastening screws, check thread, if necessary
Foreign part jammed in the air gap be-
tween useful and counter mass.
Remove foreign part
