Operation Safety
The following items are safety precautions for qualified Operator personnel:
WARNING
- Please carefully read the Safety Requirements in the “Safety Manual” before operating the robot system. Operating the robot system without understanding the safety requirements is extremely hazardous and may result in serious bodily injury and/or severe equipment damage to the robot system.
- Do not enter the operating area of the Manipulator while the power to the robot system is turned ON. Entering the operating area with the power ON is extremely hazardous and may cause serious safety problems as the Manipulator may move even if it seems to be stopped.
- Before operating the robot system, make sure that no one is inside the safeguarded area. The robot system can be operated in the mode for teaching even when someone is inside the safeguarded area. The motion of the Manipulator is always in restricted (low speed and low power) status to secure the safety of an operator. However, operating the robot system while someone is inside the safeguarded area is extremely hazardous and may result in serious safety problems in case that the Manipulator moves unexpectedly.
- Immediately press the Emergency Stop switch whenever the Manipulator moves abnormally while the robot system is operated. Continuing the operation while the Manipulator moves abnormally is extremely hazardous and may result in serious bodily injury and/or severe equipment damage to the robot system.
WARNING
- To shut off power to the robot system, disconnect the power plug from the power source or use a disconnector. Be sure to connect the AC power cable to either a power receptacle or a disconnector. DO NOT connect it directly to a factory power source.
- Before performing any replacement procedure, turn OFF the Controller and related equipment, and then disconnect the power plug from the power source. Performing any replacement procedure with the power ON is extremely hazardous and may result in electric shock and/or malfunction of the robot system.
- Do not connect or disconnect the motor connectors while the power to the robot system is turned ON. The Manipulator may move abnormally and be extremely hazardous Performing any replacement procedure with the power ON is extremely hazardous and may result in electric shock and/or malfunction of the robot system.
CAUTION
- As a general rule, the robot system should be operated by only one person. If it is necessary to operate with more than one person, ensure that all personnel communicate with each other and take all necessary safety precautions.
- Joint #1, #2, and #4: If the Manipulator is operated repeatedly with an operating angle of 5° or less, the bearings used in the joints are likely to cause an oil film shortage. Repeated operation may cause premature damage. To prevent premature damage, operate the Manipulator to move each joint to an angle of 50° or more about once per hour.
- Joint #3: If the up-and-down motion of the hand is less than 32 mm for LA3-A and less than 40 mm for LA6-A, move the joint a half or more of its maximum stroke for about once per hour.
- When the robot is operating at low speed (Speed: 5 to 20%), vibration (resonance) may occur continuously during operation depending on the combination of the arm orientation and hand load. Vibration occurs due to the natural vibration frequency of the Arm and can be controlled by taking the following measures:
- Changing the Manipulator’s speed
- Changing the teach points
- Changing the hand load
