The drive includes Safe Torque Off to remove the ability to generate motor torque when a safety event occurs, ensuring no unintended motion. This function simplifies machine safety circuits and reduces dependency on external torque-cut devices.

Ensure the supervisory network monitors safety state and alarms promptly; segregate safety-related signals from standard telemetry networks. Real-time monitoring and logging of safety events aid incident analysis and compliance.

STO allows technicians to carry out maintenance without torque generation when properly applied, reducing lockout complexity. Integrate STO checks into maintenance sign-off procedures to ensure safe re-energization after work is complete.

Commissioning includes validating STO response times, verifying interlock wiring and confirming expected behavior under simulated faults. Document measured response values and include them in the machine safety dossier.

Maintain test records of STO functional checks, wiring diagrams and configuration parameters as part of safety validation artifacts. Accurate documentation supports safe operation, future troubleshooting and regulatory audits.
