Figure 2.2: The workspace of the robot. The robot can work in an approxi-
mate sphere (Ø170cm) around the base, except for a cylindrical
volume directly above and directly below the robot base.
mounting place for the robot is chosen. Moving the tool close to the cylindrical
volume should be avoided if possible, because it causes the robot joints to move
fast even though the tool is moving slowly, causing the robot to work inefficiently
and the conduction of the risk assessment to be difficult.

2.5.2 Mounting the Robot

The robot is mounted using 4 M8 bolts, using the four 8 5
base. It is recommended to tighten these bolts with 20 Nm torque. If very ac-
curate repositioning of the robot is desired, two Ø8 holes are provided for use
with a pin. Also an accurate base counterpart can be purchased as accessory.
Figure 2.3 shows where to drill holes and mount the screws.
Mount the robot on a sturdy surface strong enough to withstand at least 10 times
the full torque of the base joint and at least 5 times the weight of the robot arm.
Furthermore the surface shall be vibration free.
If the robot is mounted on a linary axis or a moving platform then the accelera-
tion of the moving mounting base shall be very low. A high acceleration might
cause the robot to stop, thinking it bumped into something.

DANGER:
