Precautions for Safe Use of the Robot System

For the Mechanism to Be Driven

1. If the mechanism involves a risk of bodily injury to workers, set up a safety fence to prevent danger.
2. When the driven mechanism is the joint with the largest motion range, prepare adjustable mechanical stops with sufficient rigidity.
3. When the joint(s) in the mechanism has the 2nd or 3rd largest motion range in all joints, prepare joint limiters with sufficient rigidity.
4. If the mechanism involves a risk of bodily injury to workers when the brakes are released, use warning labels to alert workers to danger.
5. If it is not easy to carry the mechanism, prepare any measures for hoisting it.
6. Provide markings (e.g. labels) on the driven mechanisms to show which axis corresponds to which mechanism.

When Mounting and Connecting Motors

• For cables connecting the motor, take appropriate noise reduction measures.
• If the motor surface gets hot and the workers are at risk of touching the heated surface, attach a warning label, alerting them to the high temperature.
• Each motor shall be grounded with no more than 0.02 ohms impedance. For grounding, use a cable which dimension is 2.5mmˆ2 or larger.

For Providing Data to the User

When the motion range of the joint in the mechanism is 3rd largest or below in all joints, provide the user with the maximum stop time and distance of that joint, using instruction manuals, etc.
