Fanuc Parameter 1860 ((exclusive))

Look at the row corresponding to the axis you need to modify (X, Y, Z, etc.).

What (e.g., Mori Seiki, Doosan, Makino) is this Fanuc control on?

The External Machine Stop function, controlled by parameter 1860, plays a crucial role in ensuring the safety of operators and preventing damage to the machine. Here are some reasons why FANUC parameter 1860 is important:

Stores the current machine coordinate value for each axis using an absolute pulse coder. fanuc parameter 1860

You should modify this parameter based on the type of scale or encoder installed on your rotary axis.

Parameter 1860 is formatted as a real-time, axis-by-axis ledger input. It is configured independently for each servo axis (X, Y, Z, etc.) under the standard data profile: Specification Stage 1 Backlash Acceleration Amount Data Type Two-word (Long Integer / Axis-specific) Unit of Data Percent (%) Standard Default

Alarm 414 may appear if displayed position deviates from the expected value after modifying reference point parameters. This typically indicates that the reference position was not established correctly, often due to improper turret or rotary axis positioning. The deviation must be corrected by repeating the reference point setup procedure or adjusting grid shift parameters.

The system knows the position is invalid and requires you to perform a manual reference return.

Perform a reference position return on the relevant rotary axis. 4. Associated Parameters Here are some reasons why FANUC parameter 1860

: When a technician performs a zero-return or resets the absolute position (often by toggling the APZ bit in Parameter 1815), the system recalibrates the relationship between the machine's physical "home" and the count currently residing in Parameter 1860. Why Parameter 1860 Matters

If you change Parameter 1860, always verify the status of Parameter 1815 right next to it to ensure your zero points remain valid.

Key in the designated value according to your machine tool builder's documentation (typically 1 for standard absolute serial encoders). Press the softkey. Step 4: Power Cycle the Machine
