Removal, motor axis 1
The procedure below details how to remove the motor, axis 1.
If a shelf-mounted robot version is not flat mounted, the manipulator can contain a living
force!
Removing the motor from axis 1 may result in movement of the axis, because the brake is
released.
To avoid this, move the robot into normal calibration position or move axis 1 to get the lowest
location of the center of gravity for the upper arm.
