Fanuc Parameter 1860 Work Hot!

This parameter is used to establish the rough baseline zero position. Turning Bit 4 (APZ) from 0 to 1 tells the machine: "The position you are sitting at right now is the official home position."

This automatic updating is managed by a related setting, Parameter 1815 (specifically bit 0, labeled NRT for the rotary axis). This bit determines whether the reference point values stored in Parameters 1860 and 1861 can be changed by the control during operation . The relationship between Parameter 1860 and the absolute encoder setup is also evident in troubleshooting forums, where technicians often reset Parameters 1860 and 1861 to zero when re-establishing the absolute pulse coder's synchronization after maintenance or a battery change, with the correct values being automatically loaded once the zero-return procedure is complete .

Your Z-axis absolute home position is currently off by exactly (the tool is stopping 0.125 mm too high during tool changes). This parameter is used to establish the rough

user wants a comprehensive article on FANUC parameter 1860, focusing on how it works. This is a technical topic related to FANUC CNC controls. I need to provide detailed information about this parameter, including its function, configuration, and impact on machine operation. To cover all aspects, I will perform multiple searches to gather information about parameter 1860, including its meaning, configuration, usage, and related parameters. search results show some relevant links. Result 0 appears to be a parameter manual page mentioning parameter 1860 for reference point value. Result 1 is a Chinese Q&A site that says 1860 is for "First acceleration for Two-Stage Backlash Acc. function". Result 2 is a list of common Fanuc parameters. Result 3 is a search result for "Read Write Parameters" which might be relevant for parameter modification. Result 4 is a Focas tutorial. Result 5 is a Chinese blog post about parameter modification. Result 6 is about PMC parameters. Result 7 is a forum post mentioning 1860. Result 8 is about PMC parameters. To understand parameter 1860, I need to open result 0, result 1, result 2, result 3, result 7, and result 8. opened pages provide some information. The parameter manual page shows that parameter 1815 bit 0 (NRT) controls whether reference point values (parameter 1860, 1861) are changed or not for a rotary axis with a scale that has no revolution data. The Chinese Q&A page says 1860 is for "First acceleration for Two-Stage Backlash Acc. function". The common parameters page might list 1860 but it's not shown in the snippet. The forum posts indicate that 1860 and 1861 are involved in absolute encoder synchronization and reference point values. The search results also show that 1860 is related to "Reference point value". To further investigate, I will search for "FANUC parameter 1860 reference point". 0 might be relevant. Let's open it. page clarifies that parameter 1860 and 1861 hold reference position data for rotary axes with absolute position detectors. Let's search for "FANUC parameter 1860 1861". 3 is a Japanese blog that lists 1860 as "Value 1 for origin setting of absolute position detector". Let's open it.'s search for "1860 absolute position detector".'s search for "FANUC parameter 1860 backlash".'s search for "FANUC parameter 1860 function".'s search for "FANUC parameter 1860 PDF". need to gather more information about parameter 1860. Let's search in Chinese for "FANUC 1860 参数". also want to find information about the "Two-Stage Backlash Acc. function". Let's search for that. 6 seems promising. Let's open it. page shows that parameter 1860 is used as "1ST ACC VALUE" for the two-stage backlash acceleration function. I also need to understand "Reference point value" function. Let's search for "Parameter 1860 reference point value FANUC".'s also search for "FANUC parameter 1860 dual position feedback". search results show that parameter 1860 can have different functions depending on the model and options. I will structure the article to cover its role in absolute position detection (Reference Point Value), Backlash Acceleration (1st ACC Value), and the Two-Stage Backlash Acceleration function. I will also mention the related parameter 1861. The article will include sections on understanding the parameter, its functions, configuration, related parameters, step-by-step setup, best practices, and conclusion. I will cite the sources gathered.Mastering FANUC Parameter 1860: A Comprehensive Guide to Enhancing Machine Precision and Performance**

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.

: When setting up or "homing" a machine with absolute encoders, this parameter is changed from 0 to 1 to tell the CNC that the current physical position of the axis is the established reference (zero) point. Status Indication : The relationship between Parameter 1860 and the absolute

In Fanuc CNC systems, Parameter 1860 (APOS) stores the absolute position of each axis

To work with parameter 1860, follow these general steps:

When you swap out a servo motor or its encoder, the new unit won't have a record of the old machine zero.

Ensure the Z-axis is set to the precise height required for tool changes. An incorrect Z-axis home position will crash the tool changer arm.
