: Used for Backlash Compensation once the axis is homed.
: When manual setting is required—often for complex configurations or when adding axes—Parameter 1860 is used to assign a specific Slave Number to each axis.

Fanuc Parameter 1860 is a fundamental tool for optimizing CNC performance. By carefully adjusting this parameter, technicians can balance machine speed and movement smoothness, ensuring high-quality parts and improved productivity. Always treat parameter adjustment as a precise task, starting with small changes to find the optimal balance for your specific machine.
Bits are numbered from right to left, starting at Bit 0 (#0) up to Bit 7 (#7). Core Bit Functions
When working with parameter 1860, users may encounter issues or alarms related to incorrect settings or configuration errors. Common issues include: and back up your current settings before attempting
If the control rejects the change, jog the axis slightly in the positive direction and try again. Power cycle the machine one final time. Vital Safety Precautions
Ensure that for linear interpolation (e.g., G01), the acceleration constants (1860) for both X and Y axes are closely matched to prevent path deviation. Conclusion
When you power on a Fanuc machine equipped with absolute encoders:
This procedure is used when you have a machine with absolute encoders and need to establish or re-establish the machine's home position. This is a common task when a machine is installed, after an encoder battery has died, or after a servo motor replacement.
