Safety precautions

The precautions described below are intended to ensure the safe and proper use of the product and to prevent the user and other personnel from exposure to the risk of injury. Use the product only after carefully reading and fully understanding these instructions.

In regard to a controller, it is prohibited to start operating the robot (i.e., to operate the device in accordance with the specified purpose) when the machine in which the controller is incorporated does not meet the relevant safety standards. The factory safety manager or safety personnel in charge of the applicable machine must ensure that the machine is operated only by qualified personnel who has expert knowledge on safety, and thereby prevent injury or damage to the machine.

The term “qualified personnel” refers to persons who have received the necessary training or education and have pertinent experience; who are familiar with the relevant standards and regulations; who are authorized by the factory safety manager to engage in the necessary activities; and who have the ability to discern and prevent potential dangers.

WARNING
Handling the product without observing the instructions that accompany a “WARNING” symbol may result in serious injury or death.
CAUTION
Handling the product without observing the instructions that accompany a “CAUTION” symbol may result in injury or property damage.

General

  • Never use the product for equipment in connection with the maintenance or management of human life or health.

  • Do not use the product in explosive or corrosive environments, in the presence of flammable gases, in areas subjected to splashing water, or near combustible materials. Doing so may result in fire or injury.

  • Assign qualified personnel having expert knowledge on electrical and mechanical engineering as well as safety to the task of installing, wiring, operating/controlling, inspecting and troubleshooting the product. Handling by unqualified personnel may result in fire, injury, or damage to equipment.

  • Conduct a risk assessment in a state where all parts and components including the product have been installed in the equipment. Failure to do so may result in injury or damage to equipment.

  • Provide an interlocking guard at a position that meets the safety distance specified in EN ISO 13857 so that an operator or other personnel does not enter the movable range of the product while the equipment is operating Failure to do so may result in injury.

  • When teaching, adjusting, or inspecting the product inside the interlocking guard, take appropriate safety measures according to the results of the risk assessment of the entire equipment. Failure to do so may result in injury.

  • Provide appropriate safety measures so that the entire equipment will operate safely in the event of a system failure or malfunction. Failure to do so may result in injury.

  • Provide an emergency stop function for the equipment. Failure to do so may result in injury.

  • The function and performance of the safety-related control system are appropriately determined according to the results of the risk assessment of the entire equipment. This may result in injury.

  • Do not disassemble any components other than those specified for the motor replacement work. Also, do not modify the product. Doing so may result in injury or damage to equipment.

  • Do not disassemble or modify the product. Doing so may result in injury or damage to equipment.

  • Use the product in a condition where the entire equipment complies with relevant international standards such as ISO 12100, ISO 10218-1, ISO 10218-2, national standards, and legal regulations such as occupational health and safety required in each country. Failure to do so may result in injury or damage to equipment.

  • Perform the teaching operation outside the safety cage. Failure to do so may result in injury.

  • When an alarm of the controller is generated (any of the controller's protective functions is triggered), remove the cause before resetting the alarm (protective function). Continuing the operation without removing the cause of the problem may cause the controller to malfunction, resulting in injury or damage to equipment.

Installation and wiring

  • Install the controller inside an enclosure. Failure to do so may result in injury.

  • Keep the input power voltage of the controller within the specified range. Failure to do so may result in fire.

  • Connect the product securely according to the connection diagram. Failure to do so may result in fire.

  • Do not forcibly bend, pull, or pinch the cable. Doing so may result in fire or damage to equipment.

Operation

  • Before operating a robot, check the condition of the surrounding area to ensure safety. This may cause injury or damage to equipment.

  • Take appropriate safety measures when placing the motor in a non-excitation state. Failure to do so may result in injury or damage to equipment.

  • Do not turn off the power or input a signal to place the motor in a non-excitation state during operation. The robot may move unexpectedly, causing injury or damage to equipment.

  • Turn all input signals to the controller OFF before turning on the power supply. Failure to do so may result in injury or damage to equipment.

  • Before operating a robot, check the setting value of the parameters. Failure to do so may result in injury or damage to equipment.

  • Turn all output signals OFF before Implicit communication of EtherNet/IP is started. Failure to do so may result in injury or damage to equipment.

  • Turn off the power supply of the controller in the event of a power failure. Failure to do so may result in injury or damage to equipment.

  • Do not use the product beyond its specifications. Doing so may result in injury or damage to equipment.

  • Keep the area around the product free of combustible materials. Failure to do so may result in fire or a skin burn(s).

  • Do not leave anything around the product that would obstruct ventilation. Doing so may result in damage to equipment.

  • Keep your fingers and objects out of the openings in the controller. Failure to do so may result in fire or injury.

  • Do not forcibly bend or pull the cable that is connected to the controller. Doing so may cause damage to the product.

  • If any abnormality is observed, stop the operation immediately to turn off the power supply. Failure to do so may result in fire or injury.

  • Use a DC power supply with reinforced insulation on its primary and secondary sides for a power supply. Failure to do so may result in electric shock.

  • Do not touch the terminals while conducting the insulation resistance measurement or the dielectric strength test. Accidental contact may result in electric shock.

  • Take measures against static electricity when handling the controller. The controller uses components that are sensitive to static electricity. Static electricity may cause the controller to malfunction or be damaged, resulting in injury or damage to equipment.

  • When installing and wiring, take measures against EMC. Without effective measures to suppress Electromagnetic Interference (EMI) caused by the product in the surrounding control system equipment or Electromagnetic Susceptibility (EMS) generated by the product, the function of your equipment may be seriously affected. Verify EMC compliance with the completed equipment. Failure to do so may result in injury or damage to equipment.

  • Do not ground the positive terminal of the power supply. Doing so may result in damage to equipment.

  • Connect a 2-pole circuit breaker or 2-pole circuit protector to the power supply to protect the positive and negative terminals of it. Failure to do so may result in fire or injury.
