Does this page explicitly cover ac drive sto intent?

Yes. ac drive sto is handled as an alias intent on this canonical URL without creating a separate competing route.

Is safe torque off the same as emergency stop for every machine?

No. STO removes torque-producing power, but residual motion and stopping strategy must still be validated against machine-specific hazards.

No. STO is not electrical isolation. Follow lockout and voltage verification procedures before electrical work.

When uncontrolled coasting can create unacceptable risk, especially with high inertia or vertical-axis scenarios.

No. The tool output is engineering triage guidance and does not replace full conformity assessment or legal interpretation.

Freeze release assumptions for that axis, escalate to architecture review, then rerun validation after mitigations are implemented.

Yes. Share /safety/sto-sls#ac-drive-sto-alias to open the canonical alias section directly.
