• Protective door was open.

Click steps to track your progress.

1. 1

   Ensure all protective doors are fully closed and their interlock switches are correctly engaged before operating at speeds above the SRG limit.

2. 2

   Verify the SRG (Safe Reduced Speed) monitoring parameters in the NC control to ensure they are configured correctly for the machine's safety requirements.

3. 3

   Inspect the axis encoder feedback system for accurate speed measurement, as erroneous feedback could falsely trigger this fault.

4. 4

   Check the wiring and functionality of the protective door interlock switches to confirm they are reporting their status reliably.
