WARNING
Risk of Injury due to Unexpected Movement of Components
For vertical or slanted mounting position: when power is off, moving parts can
travel or fall uncontrolled into the lower end position.
• Bring moving parts of the product into a safe end position or secure them
against falling.
WARNING
Risk of injury due to unexpected movement of components.
• Protect the positioning range from unwanted intervention.
• Keep foreign objects out of the positioning range.
• Perform commissioning with low dynamic response.
Malfunction
Possible cause
Remedy
Loud running noises,
vibrations or rough
running of the axis.
Coupling distance too
short.
Observe permissible coupling spacings

–
Install axis without tension. Make sure that
the contact surface is flat
–
Change the layout of the attachment compo-
nent (e.g. payload).

tings.
Optimise controller data (e.g. velocity, accelera-
tion, ...).

of guide.
Lubricate the guide
Vibrations at the canti-
lever.
Operation at the reso-
nant frequency of the
axis.
–
Change the travel velocity.
–
Change the acceleration.
–
Increase axis stiffness (e.g. shorter support
distances).
–
Change the payload geometry.

Disassembly
WARNING
Unexpected movement of components.
Injury due to impacts or crushing.
• Before working on the product, switch off the control and secure it to prevent it
from being switched back on accidentally.

1) Clamping means that the clamping unit fixes the stationary cantilever at its current position.
2) The general assumption B10d = 2 x B10 is not permissible.
3) Emergency braking means braking of the moving mass, e.g. in case of power failure of the system.
