Fanuc (often abbreviated as APZ ) is used to indicate whether the zero point for an axis using an absolute pulse coder has been established. It is typically found on controls like the Fanuc 16/18/21 series and the 0i series. Function and Behavior
The behavior of Parameter 1860 is linked to Parameter 1620, which dictates the type of acceleration/deceleration—linear or bell-shaped.
When a machine tool uses absolute encoders, the control system must establish a permanent mathematical relationship between the physical scale data and the machine's true coordinate system. Parameter 1860 registers this precise baseline reference. 🛠️ The Core Mechanism: How Parameter 1860 Works

acts as a crucial foundational component within FANUC CNC systems. It records the specific zero-point offset values of the absolute position detector for each controlled axis .
Most issues related to Parameter 1860 arise after a or motor replacement.

The system will trigger a SW0100: PARAMETER WRITE ENABLE warning alarm. This is normal. Step 2: Clear the Existing Axis Calibration State
The encoder generates a reference signal (a "one-rotation signal" or grid reference) every time the motor completes a full revolution.
: Technicians determine the difference between the desired physical home position and the current absolute position reading. This difference is converted into "detection units" (pulses) and entered into 1860. Synchronization When a machine tool uses absolute encoders, the
It defines the time, measured in milliseconds (ms), that the axis takes to accelerate from 0 to the rapid traverse rate, or to decelerate to a stop.
Never attempt to force-write or manipulate parameters in the 1800-series (Axis-related parameters) without referring to the official Fanuc Parameter Manual
When you power on a Fanuc machine equipped with absolute encoders:
Using a non-contact spindle orientation sensor, they determine the spindle is stopping 0.05mm away from true zero radially. They calculate:
Depending on whether you need to shift the grid forward or backward, you will add or subtract from this number. (If shifting in the negative direction is required to lower the tool, you would subtract 125: Step 4: Input the New Parameter Value Press the hard key. Press the PARAM softkey. Type 1860 and press the No. SRCH (Number Search) softkey. Cursor over to the specific axis you are modifying.
