Universal Robots UR30 - Movement Without Drive Power

13.2. 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.
WARNING
Risks due to an unsupported robot arm breaking or falling can cause
injury or death.
•
Support the robot arm before removing power.
NOTICE
Moving the robot arm manually is intended for emergency and service
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.
