Robot Parameters

NOTICE

Set robot parameters 

Material damage due to high collision speeds, forces and pres-

sures!

 

Only combine measurement units as described in this 

manual. 

 

Carefully plan collisions and document the planning.

 

Design collision kinematics carefully and iteratively.

 

Always test at greatly reduced speeds first.

 

Then slowly increase the speeds.

 

Finally, achieve the intended operating conditions at the 

collaboration workstation.

If the robot exceeds the application limits of the force and pressu-

re sensors during the collision, material damage to the measuring 

system can result.

Consider robot operation safety settings from ISO/TS 15066.
