Emergency Stop

Definition

Safety function that immediately stops the machine.

Use the frontmatter definition as the controlled meaning for setup, machining, and inspection decisions.

Formula / Rule

• Emergency stop is a safety function: stop motion first, then preserve the scene and remove the hazard before recovery.
• Treat every E-stop as an abnormal event that requires cause confirmation, not just a button to continue production.

Typical Range

• The acceptable operating window is zero avoidable E-stop events during normal production.
• Any recurring E-stop on the same job should trigger a formal root-cause review.

Shop-floor Scenarios

• After an E-stop, confirm hazard removal, axis clearances, and restart sequence before releasing the machine.
• Record the trigger condition so the same unsafe sequence is not repeated on the next shift.

Common Errors / Troubleshooting

• If E-stop events are frequent, review guarding, interlocks, and operator sequence instead of normalizing the risk.
• If restart behavior is unclear, return to the recovery checklist and confirm every energy state before jogging axes.
