SV0475
EXCESS ERROR (MOVE:SV)
Fanuc · αi Series Servo Amplifier
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.
Repair Steps
- 1
Verify the values of parameters No. 1838 and No.1841, which define the allowable positional deviation during travel.
- 2
Inspect the mechanical system for binding, excessive load, or increased friction that could hinder smooth motion.
- 3
Check motor performance and drive tuning for the affected axis.
