Fanuc Parameter 1860 Work _top_ Online

The CNC reads the current value from the encoder.

If the stored position in 1860 suggests the machine is outside its travel limits upon startup, you may need to power on while holding "P" and "CAN" (Cancel) to bypass the check and re-home the axis. Step-by-Step: Setting the Reference Position fanuc parameter 1860 work

In Fanuc CNC systems, Parameter 1860 acts as the machine's memory for when using absolute pulse coders (APC). Unlike incremental encoders, which must hit a "limit switch" or "dog" every time the machine starts up, absolute encoders always know their position. The CNC reads the current value from the encoder

When an axis is successfully homed (set with Parameter 1815.4 APZ), the current encoder count is saved into Parameter 1860. Unlike incremental encoders, which must hit a "limit

It compares this value against the stored data in Parameter 1860 .
