In Fanuc CNC systems, the servo motor constantly works to hold its position. Even when "stopped," external forces like gravity or mechanical tension can cause slight movement. Threshold: Parameter 1829 sets the tolerance for this movement. Protection:
Results in oval-shaped circles or flat spots on radii. fanuc parameter 1829
: Typically a 2-word (32-bit) value, set individually for each axis. In Fanuc CNC systems, the servo motor constantly
: Physical binds, packed chip buildup, or a lack of lubrication in the ballscrew can prevent the axis from reaching its precise target. Protection: Results in oval-shaped circles or flat spots
: In vertical or slanted axes, check if the motor brake is failing or if there is insufficient counter-balance.
