2.9. Movement Without Drive Power
Description In the unlikely event of an emergency, when powering the robot is either impossible or
unwanted, you can use forced back-driving to move the robot arm.
To perform forced back-driving you must push, or pull, the robot arm hard to move the
joint. Each joint brake has a friction clutch that enables movement during high forced
torque.
Performing forced back-driving requires high force and cannot be performed by one
person alone. In clamping situations, two or more people are required to do the forced
back-driving. In some situations, two or more people are required to disassemble the
robot arm.

purposes only. Unnecessary moving of the robot arm can lead to
property damage.
•
Do not move the joint more than 160 degrees, to ensure the
robot can find its original physical position.
•
Do not move any joint more than necessary.
