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

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.
Procedure
Purpose
Note
1. Check travel
Determining the rotation/lifting
direction of the motor
Even with identical control, motors of the
same design can turn in opposite direc
tions due to different wiring.
2. Homing to refer
ence switch
Comparison of real situation to
the image of the control
Comply with operating instructions of the
motor drive system. Follow procedure
with limitation to low dynamic response
to reference switch:
1. Rotation,
2. Lifting motion
3. Combined rotary/lifting motion.
