Safety System Fault

What does 30 mean?

This fault encompasses diverse issues related to the drive's safety functions. It can be triggered by an active Safe Off signal preventing drive readiness, incorrect safety configuration (e.g., wrong safety switch installation, incorrect STO board placement or count, incompatibility), safety diagnostics failures (e.g., STO input status mismatch, ATEX thermistor connection issues or short circuits), or the activation of the Safe Torque Off (STO) function itself (e.g., via emergency stop). These faults indicate a compromise in the drive's ability to maintain a safe operating state and require careful investigation.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   **For Safety Diagnostics (IDs 520-522):** Inspect external safety switch inputs for differing statuses, and meticulously check ATEX thermistor connections for open circuits, short circuits, or proper operation.

2. 4

   Reset the drive and restart it. If any safety-related fault persists, contact your nearest distributor for advanced diagnostics and potential component replacement.
