Possible cause
Mechanical overloading
Service life problem
Extreme contamination under
toothed belt
Axis damaged as a result of crash
or similar
Outside the axis (e.g. drive package
including coupling or external
attachments)
Incorrect toothed belt
pretension, e.g. due to belt damage
Low temperatures result in high
viscosity of the gear grease.
Long standstill time at a position
Axis overloaded
Dynamics too high
Incorrect arrangement of the centre
of gravity of the effective load
External coupling to basic frame
or in multi−axis system
Coupling loose
Toothed belt torn or teeth broken
off
