Possible cause
Mechanical overloading
Service life problem
Excessive dirt under toothed
belt
Axis damaged as a result of
crash or similar
Outside the axis (e.g. drive
package including coupling or
external devices)
Incorrect toothed belt
tensioning e.g. due to belt
damage
Very low temperatures lead to
higher 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 work
load
External coupling on base stand
or in multi−axis system
Coupling loose
Toothed belt torn or teeth worn
Remedy

This is lost when the operating
temperature is reached.
Disappears after a start−up
phase
Observe maximum loading
values
If necessary, check modifi−
cations to project planning
Shift centre of gravity
Eliminate interference
Tighten coupling
