In FANUC CNC systems, . It acts as the software bridge between the physical servomotor encoder and the FANUC control system, dictating whether the machine operates via an absolute encoder, incremental system, or separate linear scales.
Type 1860 into the input bar and press the (Number Search) soft key.
Parameter 1860 is not a "set once and forget" value. You may need to adjust it during: fanuc parameter 1860 work
, the tool holder will bind, score, or jam inside the spindle during an M06 cycle. Instead of moving alignment dogs or brackets, engineers modify Parameter 1860 to seamlessly lift or lower the tool-change height position. 📋 Step-by-Step Guide to Changing Parameter 1860
It synchronizes the mechanical rotation of the spindle with the electrical pulses sent to the CNC. In FANUC CNC systems,
When the backup battery on your FANUC servo amplifier dies, the absolute encoder loses its memory. The CNC control immediately triggers alarms like . To clear this alarm and establish a new reference point, you must cycle Parameter 1860. The Step-by-Step Restoration Process
The 1870 function is a software option that allows users to perform complex machining operations, such as simultaneous 5-axis machining, or to enable specific hardware configurations, like a second operator panel. When parameter 1860 is set to a specific value, it activates or deactivates this function, allowing users to customize their CNC system to meet their specific needs. Parameter 1860 is not a "set once and forget" value
Fanuc CNC systems are known for their precision, reliability, and complex parameter settings. For machinists, operators, and maintenance technicians, understanding how these parameters work is crucial for maintaining machine accuracy and productivity. One such critical parameter in many Fanuc control systems (particularly older, non-absolute encoder systems or early absolute systems) is .
In conclusion, FANUC parameter 1860 plays a vital role in determining the I/O interface for the PLC in FANUC CNC systems. By understanding how this parameter works and its applications, CNC users can unlock a wide range of customization options, improving machining efficiency, productivity, and safety. By following best practices for configuration and testing, users can ensure optimal performance and reliability of their CNC machines.
. It is not typically referred to as a "work" parameter in a general sense, but rather a "reference position" or "absolute position" setting. Key Details of Parameter 1860 It stores the absolute position of each axis. Relationship with APC: APC (Absolute Position Coder)
