Set 1860 to a low value (e.g., 500).
The absolute position of the axis has not been established. This usually occurs after a battery failure in the absolute encoder or after moving the motor while the power is off. In this state, the machine will often throw a 300 APC ALARM: NEED ZRN (Zero Return). fanuc parameter 1860
This parameter sets the maximum permissible difference between the position data stored by the CNC and the data actually received from the absolute pulse coder (APC) upon power-up. Set 1860 to a low value (e
While users often interact with Parameter 1815 to set home positions, Parameter 1860 is the "under the hood" value that the CNC uses to track the physical location of each axis using an absolute encoder. In this state, the machine will often throw
Cole’s finger trembled over the button. He pressed.
What (e.g., Mori Seiki, Doosan, Makino) is this Fanuc control on?
Some machines use two dogs (deceleration + limit). Parameter 1860 still applies—the second dog merely provides safety. The speed between dogs is still controlled by 1860.
