If your system configuration uses a detection unit of , entering a value of 10000 into Parameter 1860 sets a physical deviation limit of 10.000 mm.
| Property | Details | |------------------|-----------------------------------| | | 1860 | | Axis scope | 1st axis (X) – up to 8th axis (8) | | Data type | Real / Binary (detection units) | | Unit | Detection units (usually 1 µm or 0.1 µm depending on parameter 1820) | | Default value | Usually 0 (function disabled) or a small value (e.g. 1000) | | Input range | 0 to 32767 detection units |
FANUC Parameter 1860 is a fundamental internal calculator for absolute encoder alignment. It should be treated as a of your machine's physical calibration. Always allow the CNC to manage this value natively through proper home positioning procedures or by relying on Parameter 1850 for manual adjustments.
Your Fanuc servo system operates on a "Grid" generated by the position feedback device (pulse coder, absolute encoder, or scale). As the motor rotates, the encoder sends pulses. The control identifies a specific pulse as the "Grid Point" – a reproducible position for machine zero.
According to the Fanuc Servo Motor Parameter Manual, the default or optimal values generally range between . Default Setting: 50% Recommended Starting Point: 30% - 50% Too Low: Protrusion (a small "blip" on the part) Too High: Gouge (a small indentation on the part)
Users have reported that if this procedure is interrupted—for example, by skipping the power cycle or entering values out of sequence—the control may fail with an alarm like . If you see this, go back and re-execute the full reset protocol without shortcuts.
