Parameter 1860 Work | Fanuc

Are you currently troubleshooting a or setting up a new axis on your Fanuc control? How to Enable Parameter Write Enable (PWE) on a Fanuc CNC

: The zero point is not established . This usually occurs after replacing a battery (resulting in a "300 APC Alarm") or after a motor/encoder replacement.

If they match within a certain tolerance, the machine "remembers" its position immediately without requiring a manual zero return. Troubleshooting Common 1860 Issues fanuc parameter 1860 work

Parameter 1860 determines the sign (positive or negative) of the position feedback pulses relative to the commanded movement.

Defines the exact coordinate numbers that populate the "Machine Position" display once homing is completed. Are you currently troubleshooting a or setting up

Defines the coordinate value of the second reference point (often used for tool changes). MRO Electric Enable Parameter Write (PWE)

To understand the job of Parameter 1860, it helps to look at how modern FANUC systems keep track of where components are located. On older machines using incremental encoders, axes had to travel until they tripped a physical deceleration limit switch (or dog) and found the encoder's single null mark to find home. If they match within a certain tolerance, the

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

You must re-home the axis manually and toggle Parameter 1815 (APZ bit) to 1 to re-establish the reference, which then refreshes the value in Parameter 1860 . 2. Motor or Encoder Replacement
