1.6.2 Emergency release of the robot axes
Description
In an emergency situation, the brakes on a robot axis can be released manually
by pushing a brake release button.
How to release the brakes is described in the section:
• Manually releasing the brakes on page 75 .
The robot may be moved manually on smaller robot models, but larger models
may require using an overhead crane or similar equipment.
Increased injury
Before releasing the brakes, make sure that the weight of the manipulator does
not result in additional hazards, for example, even more severe injuries on a trapped
person.
DANGER
When releasing the holding brakes, the robot axes may move very quickly and
sometimes in unexpected ways.
Make sure no personnel is near or beneath the robot.
