| NRT Bit Setting | Parameter No. 1860/1861 Behavior | |---|---| | 0 (Default) | – The control will update parameters 1860/1861 with the current reference position as needed. | | 1 (Set) | Reference point value is not changed – Parameters 1860/1861 remain fixed; useful when using a scale that has no revolution data. |
). If the value is too small, the machine will "nuisance trip" on minor vibrations. If it is too large, the machine might allow dangerous mechanical drift before stopping. 3. Comparison: 1860 vs. 1828 It is common to confuse Parameter 1860 with Parameter 1828. fanuc parameter 1860 full
The machine zeros out, but the "Machine Coordinate" is not zero. | NRT Bit Setting | Parameter No
Do not attempt to force a value into Parameter 1860. On most systems, it is . To change the machine's reference position, use the proper zero-point setting procedure involving Parameter 1815. To change the machine's reference position
