In the case of heavy or medium effective loads or at high and medium slide
speeds:
· Use shock absorbers of sufficient dimensions.
The integrated buffers are not intended as continuous cushioning
components.
With mass geometries with projection in the
longitudinal direction of the cantilever axis:
· Make sure that the effective load does not
strike against the drive head or the
(geared) motor when it moves into the
end position.
Ascertaining the approach direction of the cantilever:
1. Start check travel limited to low dynamics.
For reasons of safety the cantilever arm always starts from a stable position.

In spite of equal control, even motors of the same design sometimes turn in
the opposite direction due to wiring.

Type of travel:
2. Start reference travel at low cantilever arm speed from the stable position in
the direction of the reference switch.
