Accumulated metal chips, a lack of way lube, or a physical bind in the ball screw.
allowable positional deviation (error) while the axis is stopped fanuc parameter 1829
FANUC Parameter 1829 serves as a digital watchdog, ensuring your machine axes move precisely in lockstep with the controller's instructions. When an SV 0411 alarm occurs, it is an indication that the balance between mechanical friction, electrical drive power, and software constraints has been disrupted. By utilizing the diagnostic screens, verifying physical machine condition, and calculating appropriate safety margins, you can optimize Parameter 1829 to ensure both maximum productivity and machine safety.
