1860 Hot! | Fanuc Parameter

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.

When a CNC machine commands a rapid move (G00), the axis cannot instantly jump from zero to maximum speed. It must accelerate to that speed and then decelerate to a stop. The shape of this speed curve is determined by the Time Constant. fanuc parameter 1860

: The machine will typically go into an Emergency Stop or P/S 100 state while PWE is enabled. For one terrible second, nothing happened

: Alarms such as "APC Alarm: Need ZRN" often indicate a mismatch or loss of the data stored in this parameter. How to Modify (If Required) The spindle warmed up

In FANUC CNC systems, Parameter 1860 a critical coordinate-related parameter used to store the current position of an axis when using an absolute pulse coder (APC)
