WARNING
Uncontrolled moving mass if there is a power failure.
Injury due to impacts or pinching.
• Ensure that nobody can place his/her hand in the
path of the moving components (e.g. through pro­
tective crate).
• Ensure that no foreign objects are located in the
positioning range.
It should not be possible to touch the EHMB until
the load has come to complete standstill.
The cover aC serves to protect the drive shaft
(è 9 Accessories).
Note
Excessive driving torque or axial force will destroy the EHMB.
• Comply with maximum permissible driving torque or axial force of the EHMB.
The motor current may need to be limited.
Note
With excessive rotation (e.g. endless rotation), the energy supply to the attachment
components may be interrupted. This can cause held loads to fall down (e.g. if the
tubing line of a pneumatic gripper comes loose).
• Check whether mechanical or electric safety measures are necessary.
