To understand its purpose, it helps to break down how a FANUC servo system operates:
Step down Parameter 1829 in increments of 500 (e.g., from 3000 down to 2500). Test the homing cycle after each power cycle until the vibration stops. Conclusion fanuc parameter 1829
: Once that gap (positional deviation) exceeds the value you’ve tucked away in Parameter 1829 , the machine triggers an Excess Error (Stop) alarm to prevent potential crashes or inaccurate cuts when it starts moving again . Why You Might Need to Visit 1829 To understand its purpose, it helps to break
Press the key, then press the right arrow softkey until you see [DIAGN] (Diagnosis). Why You Might Need to Visit 1829 Press
sets the position deviation limit when the axis is stopped (at a standstill).
: Noise in the feedback cable or a "dirty spot" on scales can feed the CNC incorrect position data, making it think the axis has moved when it hasn't. External Forces
If the axis typically shows a following error of 10 μm when settling into position (as viewed on the servo monitor screen), a setting of (representing 30 μm or 0.030 mm) would provide a safety margin of 3×.
