: Maintenance technicians use this parameter to verify that the absolute pulse coder is correctly tracking the machine's physical position. 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. Absolute encoders rely on a backup battery to

bits), which tells the system that an absolute pulse coder is being used and whether the reference position has been established. Coordinate Synchronization After replacing batteries

: In standard procedures, manually performing a reference return after setting 1815.4 to '0' will cause the CNC to automatically update the value in Parameter 1860 and then flip 1815.4 back to '1'. How to Set or Reset Parameter 1860

After a severe crash or over time, the mechanical zero may drift. Instead of moving limit switches, you can shift the reference position via Parameter 1860. However, this is a band-aid, not a repair . For significant shifts, fix the mechanics first.

: If the absolute pulse coder (APC) batteries die, the absolute position is lost. After replacing batteries, you must move the axis to its physical home and toggle Parameter 1815 bit 4 (APZ) to "1". This action updates Parameter 1860 with the new zero-point data. Parameter Backup
