The Role and Impact of FANUC Parameter 1829 in CNC Systems In the sophisticated world of Computer Numerical Control (CNC), precision is maintained through a delicate balance of electrical commands and mechanical feedback. Among the thousands of settings that govern a FANUC control system, serves as a critical safety and precision threshold, specifically defining the limit for positional deviation (excess error) while an axis is in a stopped state . Defining Parameter 1829: Excess Error (Stop)

(labeled as "Position Error Limit when Stopped" ) is a critical safety setting that defines the maximum allowable deviation between the commanded position and the actual position while an axis is at a standstill. Function and Impact

Results in oval-shaped circles or flat spots on radii.
