Fanuc Parameter 1860 =link= Jun 2026

Change the value from 0 to 1 . The control will issue a flashing P/S 100 PARAMETER WRITE ENABLE alarm. This is normal. Step 2: Navigate to Parameter 1860 Press the hard key. Press the PARAM soft key. Type 1860 and press the No. SRH (Number Search) soft key.

This bit tells the system if the reference position (zero point) has been established. When you set the home position manually, the system updates Parameter 1860 with the current coordinate and then automatically flips the APZ bit to "1" to confirm the zero point is set. en.industryarena.com When to Modify or Check Parameter 1860 Losing Home Position:

: The value in 1860 often uses modular arithmetic, meaning the count "wraps around" once it reaches a certain limit based on the encoder's resolution. Relationship to Zeroing

Unlike simple ON/OFF parameters, . The correct value depends on: fanuc parameter 1860

In FANUC troubleshooting, Parameter 1860 is rarely discussed without mentioning . They work hand-in-hand to manage absolute positioning.

As the machine homed successfully and the alarms vanished, Sarah reminded the crew: . If that battery dies, that memory vanishes, and you're back to manual alignment and clocking holes just to get the spindle moving again.

The cause was a mystery. A power blip? A failing battery in the servo amp? A gremlin? All Cole knew was that Goliath was catatonic. Change the value from 0 to 1

More precisely, Parameter 1860 defines the for the spindle’s position control loop during orientation mode. It is a dimensionless integer value, typically ranging from 0 to 3000 , though typical operational values fall between 500 and 2000.

, which establishes the zero point), Parameter 1860 is typically or updated automatically by the system. Modular Arithmetic

A: No. Spindle parameters require a power cycle. Changing 1860 without reboot has no effect. Step 2: Navigate to Parameter 1860 Press the hard key

Note: If you replace the battery while the CNC is powered , you will keep your position data. If you replace it while the CNC is OFF , you will lose the position data, forcing you to re-calibrate using parameters 1860 and 1815. 3. Alarm 309 (APC Alarm: DVD Turn)

In the world of FANUC CNC systems, Parameter 1860 is a critical, though often misunderstood, data field that serves as the digital link between the machine's physical location and its internal coordinate system. For technicians and engineers, mastering this parameter is essential for maintaining the high-precision "memory" of a machine tool. The Role of Absolute Position Detectors

The technician graphed the position error and saw a slow, sluggish settling (underdamped). After three iterations – 950 → 1350 → 1650 → 1500 – the orientation completed in 0.35 seconds with no overshoot.
