What is the typical effect of a fault on robot motion?

• A. A fault stops motion and requires a reset.
• B. A fault triggers a warning but continues.
• C. A fault has no effect on motion.
• D. A fault is only a software notice.

Answer: (A)

When a fault occurs, the robot system immediately stops all motion to protect people and equipment. The fault is latched and won’t allow movement again until you perform a reset or clear the fault condition, reinitializing the safety state before motion can resume. This is the standard behavior because faults indicate unsafe or abnormal conditions that must be acknowledged and resolved before continuing.

Warnings or notices that don’t halt motion exist in some cases, but they’re not the same as a fault. A fault specifically pauses or disables movement to prevent damage or injury, and a reset is typically required to clear it. A fault having no effect on motion or being only a software notice would defeat the safety purpose of fault handling, so they don’t fit the typical behavior.
