Which statement is true about interference zones triggering outputs?

• A. They trigger an output signal when the TCP is outside the zone
• B. They trigger no outputs
• C. They reset the robot’s position when inside the zone
• D. They trigger a specific output when the TCP is inside the zone

Answer: (D)

Interference zones are defined regions in the robot’s workspace that the controller watches relative to the Tool Center Point. You can configure a specific I/O signal to assert when the TCP is inside such a zone, signaling that the tool is occupying or entering the restricted/critical area. This behavior is what makes the statement true: a designated output is triggered while the TCP is inside the zone. This signaling is useful for safety interlocks or process control, where entering the zone should notify downstream systems or pause actions. The other options describe signals that don’t align with how zone signaling is typically used: triggering only when outside the zone, triggering no outputs, or resetting the robot’s position inside the zone.
