Mechanical Operation and Maintenance Manual for ER20-1100 Industrial Robot
7
Approach the robot cautiously.
Press emergency stop button or cut off power, so the robot cannot make movement when
it’s not operation.
A supervisor (the third person) should be assigned to monitor the safety and be able to
immediately press the emergency stop button during robot’s movement.
Robot in operation should be stopped by emergency stop button at any time.
In order to comply with these principles, it is necessary to fully understand the following
precautions and follow them.
1.1.2 Safety countermeasures for robot
Unnecessary protrusions or sharp parts should be removed in robot design. Materials that
suit the working environment and safety protective structures against faults that are not
prone to damage or accidents during movements should be used. Additionally, safe
operation should be ensured by installing misoperation detection stop and emergency
stop functions, and interlocking function to avoid dangers when peripheral equipment
acts abnormally.
The body is a multi-joint mechanical arm structure, and the angle of each joint constantly
changes during movement.
If it is necessary to approach the robot for teaching and other work, be careful not to be
clamped by joints. The end of each joint’s movement is equipped with a mechanical stop,
which is highly risky for being clamped. Therefore, special attention should be paid to.
The arm may fall due to gravity or move to an uncertain direction if the servo motor is
removed or the break is released. Therefore, preventative measures must be implemented
and the surrounding safety conditions must be endured before operation.
