  • Page 3: Safety Precautions

    Safety precautions The precautions described below are intended to prevent danger or injury to the user and other personnel through safe, correct use of the product. Use the product only after carefully reading and fully understanding these instructions. It is prohibited to start operating the actuator (i.e., to operate the device in accordance with the specified purpose) when the machine in which the actuator is incorporated does not satisfy any relevant safety standards.
  • Page 4 • Do not use the product in explosive or corrosive environments, in the presence of flammable gases, locations subjected to splashing water, or near combustibles. Doing so may result in fire, electric shock or injury. • Do not transport, install the product, perform connections or inspections when the power is on.
  • Page 5 • Provide an emergency stop device or emergency stop circuit externally 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. • When the driver was replaced, set parameters such as the resolution, moving direction and others before operating the actuator.

  • Page 7 Names of parts The moving part of the actuator is shown in gray color. „ Guide type Do not remove the joint from the ball screw shaft. Doing so may deteriorate the installation accuracy of the ball screw shaft, resulting in malfunction. In addition, if the joint is removed, the home position which has been set in the encoder (ABZO sensor) at the time of shipment may deviate.

  • Page 8: Precautions For Use

    Precautions for use This section covers limitations and requirements the user should consider when using the product. z General • Always use an accessory cable to connect the actuator and driver. • Be sure to provide an anti-spin mechanism for the non-guide type actuator. The actuator cannot be operated without the anti-spin mechanism because the ball screw rotates idly.
  • Page 9 z Temperature • In order to protect the encoder (ABZO sensor), use the actuator so that the surface temperature on the motor case does not exceed 80 °C (176 °F). If the surface temperature on the motor case may exceed 80 °C (176 °F), improve the operating conditions such as ambient temperature, operating speed, duty cycle and others.
