Fanuc Parameter 1829 Jun 2026

sets the position deviation limit when the axis is moving . Because an axis requires more tolerance to accelerate, decelerate, and fight cutting forces while moving, the value in 1829 is almost always significantly larger than the value in 1828. The Consequence: Alarm SV0411 (Excess Error)

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) fanuc parameter 1829

: Press the SYSTEM function key, then the PARAM soft key. Type 1829 and press NO.SRH . sets the position deviation limit when the axis is moving

Applies a small, programmed "jump" when an axis reverses direction. Among the thousands of settings that govern a

If Parameter 1829 is set too low, the motor will lag behind its commanded position during the homing routine. If the lag exceeds the limit set in Parameter 1828 (Position Deviation Limit during movement), the CNC throws a servo alarm. 2. Axis Overshoot or Oscillating (Vibrating)
