Every CNC axis operates on a closed-loop servo system. The CNC command module calculates where the axis should be, and the encoder tracks where the axis actually is. The difference between these two values is the positional deviation (following error).
Reset the CNC or perform a power cycle if required by the control model. fanuc parameter 1829
The axis cannot stop fast enough due to a time constant that is too short for the current feedrate. Mechanical Wear: Every CNC axis operates on a closed-loop servo system
FANUC Parameter 1829 is your machine's protective ceiling against excessive movement lag. Keeping it properly balanced ensures that your CNC operates with high accuracy during complex interpolations while maintaining the ability to shut down safely if a mechanical bind or electrical failure occurs.

Remember: Parameter 1829 does not fix mechanical problems. It only tells you when they exist. Use it wisely, and your FANUC-controlled machine will deliver years of reliable, alarm-free production.
Parameter 1829 ensures that when the CNC switches into rigid tapping mode (G84 or G74), the position loop gains of both the driving linear axis and the spindle are clamped to a matching, synchronized value. Key Specifications of Parameter 1829:
