EXCESS ERROR (STOP:SV)

What does SV0474 mean?

The servo detected that the positional deviation during stopping exceeded the parameter (No. 1839, No.1842) setting value. This indicates a failure of the axis to hold its commanded stop position within tolerance, potentially due to mechanical issues or incorrect tuning.

• The position error has become excessively large during a stop command.
• The servo drive failed to reach the commanded stop position within tolerance.
• A sudden mechanical load or external force caused significant position deviation.
• Parameter P500.1 (Position Error Limit) is too small for the stop maneuver.

Click steps to track your progress.

1. 1

   Verify the values of parameters No. 1839 and No.1842, which define the allowable positional deviation during stopping.

2. 2

   Inspect the mechanical brake for proper operation and wear on the affected axis.

3. 3

   Check for external forces, excessive load, or increased friction that could cause unexpected movement while stopped.
