Fanuc Parameter 1860 Full [2021] -
The reference position is established . The system knows exactly where the axis is located based on the absolute encoder data. 2. When Does Parameter 1860 Revert to 0?
(often referred to as APZ ) is a critical configuration setting in Fanuc CNC systems (such as the Series 0i, 16i, 18i, and 31i) that indicates whether the reference position for an absolute pulse coder has been established for a specific axis.
Parameter 1860 is a where each bit typically corresponds to a different controlled axis (X, Y, Z, etc.). fanuc parameter 1860 full
Absolute encoders rely on a backup battery to "remember" their position when the power is off. If the battery dies, the position is lost.
A technician may manually change this bit to "0" to force a new home position calibration. 3. How to Set or Reset Parameter 1860 The reference position is established
Understanding Fanuc Parameter 1860: Absolute Position Detection
In a perfectly functioning machine, this parameter stays at "1" indefinitely. However, certain events will force it to "0," requiring a re-homing procedure: When Does Parameter 1860 Revert to 0
If you disconnect the motor from the ball screw, the physical relationship between the encoder and the machine zero changes.
When a machine is equipped with absolute encoders, it does not require a manual "home" or zero-return operation every time it is powered on, provided the absolute position is correctly saved. Parameter 1860 is the system's "flag" that tells it whether this position is currently valid. 1. The Core Meaning of Parameter 1860
The reference position is not established . The machine does not know its absolute zero, and you will likely see a "Need ZRN" (Zero Return) alarm or a 300-series absolute pulse coder alarm.
