Fanuc Parameter 1829 [new] – Secure

Following error at rapid = 800 / 33.3 ≈ 24 mm! But 1829 = 3 mm. Every rapid retraction caused a 24 mm error but the alarm fired at 3 mm – instant fault.

Parameter 1829 sets the maximum allowable threshold for this following error while the axis is actively moving.

: Always write down the original parameter values for every axis before making any modifications so you can revert back if needed. fanuc parameter 1829

Fanuc defines the Positioning Deviation Limit for each axis in the stopped state . It serves as a safety threshold to ensure that a stationary axis does not drift beyond a specific tolerance due to external forces or mechanical issues. Core Function

When a servo axis stops moving, the CNC expects the motor position—monitored by the encoder—to remain exactly at the commanded position. If the machine senses that the axis has moved away from this commanded position (a "positional deviation") while stopped, and that movement exceeds the value defined in Parameter 1829, the NC will trigger an emergency stop alarm. Servo Loop Gain/Error Handling. Following error at rapid = 800 / 33

If an axis (like a vertical Z-axis) drops slightly due to gravity after the brakes or servos are disabled. en.industryarena.com How to Modify (General Procedure)

When there is a mismatch or data entry error in Parameter 1829, the machine will usually refuse to enter a "Ready" state or will throw a servo-related error during startup or axis initialization. Parameter 1829 sets the maximum allowable threshold for

Fanuc Parameter 1829 is a specific setting that can be adjusted on Fanuc CNC machines. The parameter is also known as " Scaling factor for pitch error compensation". In simple terms, it is used to adjust the scaling factor for pitch error compensation on the machine's axis.
