  • 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 cage with interlock, 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 allow your hands to be caught in moving parts of 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 EN ISO 12100, EN ISO 10218-1, EN 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.

  • 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 install, connect, or inspect/troubleshoot the product while the power is on. When working with the power on state, provide work rules in accordance with the Ordinance on Industrial Safety and Health and take appropriate safety measures. Failure to do so may result in fire, injury, or damage to equipment.

Installation and wiring

  • When transporting or installing the product, wear a helmet, safety shoes, gloves, or other protective equipment to hold the specified places. Failure to do so may result in injury.

  • Be sure to secure the product itself according to the instructions. Failure to do so may result in injury or damage to equipment.

  • Be sure to wire and connect according to the instructions. Failure to do so may result in fire or damage to equipment.

  • Do not pull the cable and connector, apply excessive force to them, or step on them. Also, do not excessively bend the cable. Doing so may result in injury or damage to equipment.

  • Depending on the operating environment, the cable between the product and the controller may be damaged or deteriorated. Therefore, protect the cable with a protective tube or cover as necessary. Failure to do so may result in injury or damage to equipment.

  • Make sure that two or more people work together to perform the necessary tasks when installing the product. Also, when working with two or more people, clarify the relationship and roles of the primary worker and assistant worker, while communicating with each other to ensure safety. Failure to do so may result in injury.

  • Install an external fuse, if necessary, to prevent ignition due to a large amount of current flowing from the power supply side.

Operation

  • 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.

  • Check the condition of the surrounding area to ensure safety. This may cause injury or damage to equipment.

  • When turning on the driver power, make sure there is no signal input from the host controller. The product may start operating unintentionally, causing injury or damage to equipment.

  • Turn off the power supply of the driver in the event of a power failure. Otherwise, the product may start suddenly when the power is restored, causing injury or damage to equipment.

  • If any abnormality is observed, immediately stop operation and turn off the power to the motor that drives the product. 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.

  • When operating the product after the driver power supply is turned on or the power to the motor is turned off, adjust the position at low speed to ensure safety. Failure to do so may result in injury or damage to equipment.

Maintenance and inspection

  • Perform the pre-work (daily) inspection and periodic inspection according to the instructions in this manual, and check that there are no abnormalities in the product and related equipment before working. 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.

  • When conducting the insulation resistance measurement or the dielectric strength test, be sure to separate the connection between the product and the driver. Failure to do so may result in damage to equipment.

  • Take measures against static electricity when handling. Static electricity may cause the encoder (ABZO sensor) of the motor that drives the product or the driver to malfunction or be damaged. This may result in injury or damage to equipment.

  • Stop operation if abnormal noise or vibration occurs during operation. Failure to do so may result 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 or driver to the surrounding control system equipment and Electromagnetic Susceptibility (EMS) generated by the product or driver, the function of your equipment may be seriously affected. Verify EMC compliance with the completed equipment. This may result in injury or damage to equipment.

  • Since the motor surface temperature may exceed 70 °C (158 °F) even under normal operating conditions, if the operator is allowed to approach the motor, affix a warning label shown in the figure on a conspicuous place. The surface is hot, and this may cause a skin burn(s).

  • Use a driver and cable that are connected to the motor only in the specified combination. Failure to do so may result in fire, injury, or damage to equipment.

  • Keep the encoder (ABZO sensor) of the motor away from a strong magnetic field. This may damage to the encoder (ABZO sensor) or cause the product to malfunction. Injury or damage to equipment may result.

  • To protect the encoder (ABZO sensor), use the motor in a condition where the motor surface temperature does not exceed 80 °C (176 °F). Failure to do so may result in damage to equipment.

  • Make sure not to apply a strong shock to the encoder (ABZO sensor) of the motor. This may damage to the encoder (ABZO sensor) and cause the product to malfunction, resulting in damage to the equipment. The label shown in the figure is affixed on the motor.

  • Be careful not to make any mistakes in the combinations when connecting a motor and a driver. Wiring in the wrong combination may cause unexpected movement. This may result in injury or damage to equipment.

  • The status of the actuating controls shall be clearly indicated, e.g. power on, fault detected, automatic operation. If an indicator light is used, it shall be suitable for its installed location and its color shall meet the requirement of IEC 60204-1.

  • Be careful not to get your fingers caught by the stopper (1 place) that limits the movement of the product's 1st axis (M1). Failure to do so may result in injury. The label shown in the figure is affixed on the stopper part.

  • Hold the cover firmly to prevent it from falling, when removing the tape from the cover. Failure to do so may result in injury or damage to equipment.

  • Be sure to attach the cover after wiring. Failure to do so may result in injury or damage to equipment.
