CC SBH rot. speed too high %1

What does 231-A840 mean?

This error indicates that the maximal permissible velocity of the standstill monitoring (SBH - Safe Brake Hold or Safe Operating Stop) was exceeded. This means the system detected motion when it should have been at a standstill or within a very low-speed threshold.

• The maximal permissible velocity of the standstill monitoring (SBH) was exceeded.
• Drive is still moving or rotating above the allowed threshold when SBH is active.
• Faulty encoder or feedback system providing incorrect speed information.
• Incorrect standstill monitoring parameters.

Click steps to track your progress.

1. 1

   Verify that the drive and axis are indeed at a complete standstill when SBH is activated.

2. 2

   Inspect the drive system for any unintended movement, binding, or external forces causing motion.

3. 3

   Check the encoder feedback system for the affected drive; inspect the encoder itself, its wiring, and connections for damage or signal integrity issues.

4. 4

   Review parameters related to standstill monitoring (SBH) velocity thresholds and ensure they are configured correctly for the application.

5. 5

   Observe the actual speed feedback in diagnostics to confirm its accuracy when SBH is active.
