It works in tandem with the absolute pulse coder (APC) on the motor to ensure the machine coordinate system matches the physical location of the table or tool. fanuc parameter 1860

For one terrible second, nothing happened. Then, with a familiar, powerful hum, the C-axis rotated smoothly to its home position and locked with a solid clunk . The tool changer cycled. The spindle warmed up. Are you currently troubleshooting a or trying to

A: OEMs often set 1860 for maximum stiffness to guarantee tool change reliability, even at the cost of a slight vibration. You can usually reduce it by 10-15% for smoother operation, but confirm with them first. | Practical Machinist It works in tandem with

Parameter 1860 is far more than a simple number in a FANUC parameter list. It is a precision tuning tool that balances cycle time against positional repeatability. Too high, and you risk inconsistent homing and alarms. Too low, and you waste seconds on every startup—seconds that add up to hours of lost productivity over a machine's lifetime.

Cycle time per part reduced by 2.1 seconds, and tool change faults dropped to zero.
