CC SBH rot. speed = 0 %1

What does 231-A850 mean?

This error indicates that standstill monitoring (SBH) was set to 0. This typically means the parameter defining the maximum permissible velocity for standstill monitoring is configured as zero, essentially disabling monitoring or causing an unexpected error, possibly due to an internal software issue or incorrect transmission settings.

• Standstill monitoring (SBH) was set to 0 (parameter for maximum permissible velocity).
• Internal software error.
• Incorrect CfgAxisHardware->transmission (traverse per motor revolution) parameter value set to 0, which affects speed calculation.

Click steps to track your progress.

1. 1

   Check the parameter setting for standstill monitoring (SBH) velocity threshold; ensure it is set to a non-zero, appropriate value.

2. 2

   Verify the CfgAxisHardware->transmission parameter (traverse per motor revolution) for the affected axis and ensure it has a correct, non-zero value.

3. 3

   Inspect the drive and motor for any mechanical issues that might prevent accurate speed feedback, even if standing still.

4. 4

   If the issue persists, consider reloading the safety configuration and/or updating the controller's software to rule out internal software errors.
