FANUC Dual Check Safety (DCS)

Dual Check Safety (DCS) Position and Speed Check continuously monitors robot motion using redundant, certified safety processors to ensure safe operation at all times. The system actively verifies robot position and speed, and immediately removes motor power if programmed position limits are exceeded or speed thresholds are violated. This fast response helps prevent unsafe conditions before they can pose a risk to personnel or equipment.

By enabling advanced safety functions such as safe work zones, speed‑limited areas, and dynamic safety behavior, DCS Position and Speed Check allows precise control of robot motion without the need for external safety sensors or additional hardware. Safety parameters can be configured to match specific application requirements, supporting flexible cell layouts and intelligent safety strategies.

Designed for complex automation environments, this solution provides highly accurate, configurable protection while fully complying with international functional safety standards.

Dual Check Safety (DCS) Basic Position Check restricts robot motion to predefined safe areas by continuously monitoring the robot’s position using redundant, certified safety processors. If the robot exceeds the programmed position limits, motor power is immediately shut off, helping to prevent unsafe conditions and protect personnel working near the robot. This fast and reliable response ensures essential position-based safety without relying on external sensors or additional hardware.

By using internal position feedback and built-in safety monitoring, Basic Position Check provides a simple and effective safety solution for applications requiring fixed safety boundaries. The configuration process is straightforward, making it well suited for standard robotic cells with consistent operating zones. Designed to meet international functional safety standards, DCS Basic Position Check offers certified, reliable protection while simplifying system design and reducing overall installation complexity.
