DENSO Safety Motion

Working near DENSO robots safely is possible thanks to the Safety Motion function of the new RC8A robot controller. This function enables users to define virtual fences around the work environment and thus regulate the robot’s activity when a person enters into predefined safety zones.

The system uses optical sensors to dynamically control robot speed in relation to the distance of approaching individuals.


Stop Monitoring

  • Stops robot motion when personnel are detected
  • Returns robot to operation immediately after personnel leave

Speed Monitoring

  • Limits robot operation speed to safe level when sensor detects personnel entering a specified area

Operation-Area Monitoring

  • Limits robot operation area to personnel working area
  • Personnel and robot can both approach common operation area

The DENSO Safety Motion function is a cutting-edge tool for maximizing industrial robot safety and is offered as an option with the RC8A robot controller. Optical sensors are employed to dynamically control robot speed in relation to the distance of approaching individuals, making working environments with robots safer for humans. The sensors, one placed at the bottom and one at the top of the automation cell, generate virtual safe zones. The green and yellow zones are farthest from the robot and the red zone is closest. Entry into the green and yellow zones triggers speed reductions, while entry into the red zone stops the robot entirely.
