EXCESS ERROR (MOVE:SV)

What does SV0475 mean?

The servo detected that the positional deviation during traveling exceeded the parameter (No. 1838, No.1841) setting value. This indicates the axis is not accurately tracking its commanded trajectory during motion, suggesting a problem with motor power, feedback, or mechanical resistance.

• Excessive accumulated error in the servo loop (SV).
• Parameter P1-54 (maximum servo error) exceeded.
• Potential servo motor winding or encoder issue.
• High load or unexpected mechanical resistance.

Click steps to track your progress.

1. 1

   Verify the values of parameters No. 1838 and No.1841, which define the allowable positional deviation during travel.

2. 2

   Inspect the mechanical system for binding, excessive load, or increased friction that could hinder smooth motion.

3. 3

   Check motor performance and drive tuning for the affected axis.
