4.1 Introduction

This chapter describes the basics of mounting the parts of the robot system. Electrical installation
instructions in chapter 5 must be observed.

4.2 Workspace of the Robot

The workspace of the UR5e robot extends 850 mm from the base joint. It is important to consider
the cylindrical volume directly above and directly below the robot base when choosing a mounting
place for the robot. Moving the tool close to the cylindrical volume should be avoided because it
causes the joints to move fast even when the tool is moving slowly, which causes the robot to work
inefficiently and makes it difficult to conduct a risk assessment.

4.3 Mounting

Robot Arm The Robot Arm is mounted using four 8.8 strength, M8 bolts and four 8.5 mm mount-
ing holes at the base. The bolts must be tightened with 20 N m torque.
Use the two Ø8 holes provided, with a pin, to accurately reposition Robot Arm. Note: You can pur-
chase an accurate base counterpart as an accessory. Figure 4.1 shows where to drill holes and
mount the screws.
Mount the robot on a sturdy, vibration-less, surface that can withstand at least ten times the full
torque of the base joint and at least five times the weight of the Robot Arm. If the robot is mounted
on a linear axis, or a moving platform, then the acceleration of the moving mounting base is very
low. A high acceleration might cause the robot to make a safety stop.
