Fanuc Parameter 1860 Full ^hot^ Jun 2026

-axis home position is reset, the value in 1860 changes, which may require you to re-verify the tool change height stored in Parameter 1241 en.industryarena.com How to View/Set Enable Writing : In MDI mode, go to the screen and set PARAMETER WRITE = 1 : Press the hard key, then the to locate the parameter for each axis.

Many Fanuc controls offer a mode (parameter 1802 bit 4 and parameter 1850). If bell-shaped ACC/DEC is active:

In modern Fanuc systems—including the Fanuc Series 0i-F , 16i, 18i, 21i, and 30i models—Parameter 1860 holds the relationship data between the machine's reference physical coordinates and the underlying internal counter value of the absolute encoder. Data Attribute Specifications 1860 (Value 1 for Absolute Position Detector Zero Point) Input Type Locked / System-Calculated Parameter Data Type 2-word axis (Long Integer) Companion Settings Parameter 1861 (Value 2), Parameter 1862 (Value 3) The "Do Not Touch" Rule

If your machine is constantly tripping a alarm during rapid movements, Parameter 1860 is flagging a genuine system failure. While you can temporarily increase the value in Parameter 1860 to diagnose the issue, the root cause is rarely the parameter itself. Look for these common mechanical and electrical issues: 1. Mechanical Binding or Heavy Friction fanuc parameter 1860 full

Select the axis you want to adjust (X, Y, Z, etc.) and input the new value.

Parameter 1821 (Reference Counter Size) must always match or cleanly divide into the feedback resolution cycle defined by Parameter 1860. If they do not align, the machine will fail to establish a repeatable home position.

Configuration, Function, and Troubleshooting of Parameter 1860 Applicable Systems: FANUC Series 16i, 18i, 21i, 30i, 31i, 32i, 0i-TD/TF, 0i-MD/MF Category: Servo Initialization / Axis Setting -axis home position is reset, the value in

If the machine recently underwent a motor or encoder replacement, the loop gain parameters (such as Parameter 1825) might be set too low. If the position loop gain is too low, the servo responds sluggishly to commands, generating a naturally larger deviation that breaches the 1860 threshold. Best Practices and Factory Guidance

Some control models include Parameter 1860 as a when a two-speed gearbox is present on the axis drive. This is particularly true for older 18MC controls where parameters 1853, 1855, 1856, 1860, 1861, and 1865 are listed in the same axis format but standard manuals skip to 1870. In those legacy systems, 1860 can store one of the gear ratio numerator/denominator pairs.

: The alpha/beta servo motors use internal pulse coders kept alive by lithium batteries when the main breaker is flipped off. Data Attribute Specifications 1860 (Value 1 for Absolute

Adjusts the electrical reference position by a specific number of pulses (detection units). Data Type: 2-word (Signed long integer).

Note: Always refer to your specific FANUC maintenance manual (B-63944EN, B-63525EN, etc.) as parameter mapping and bit assignments can vary between series and firmware versions.

In FANUC CNC controls, maintaining precise position tracking is essential for modern manufacturing. FANUC Parameter 1860 plays a vital role in this capability. It defines the .
