CNC systems do not establish home positions solely using physical mechanical switches. Instead, the physical ramp (deceleration dog) signals the servo motor to slow down and look for the absolute physical marker pulse inside the motor's encoder. 2. The Role of Parameter 1850 and 1860
: When bit 4 of parameter 1860 (APRS) is set to 1 , it indicates that the reference position for that axis has been established. If it is 0 , the CNC does not know the absolute machine position and will typically require a "homing" or reference return procedure. fanuc parameter 1860 work
Because the encoder's marker pulse may not line up perfectly with the physical zero point of the machine structure, software adjustments are required. CNC systems do not establish home positions solely
Fanuc (labeled as APRS ) is a critical setting used to establish the reference position (home position) for axes equipped with absolute encoders. It functions by signaling to the CNC whether the reference position for a specific axis has been successfully established and "remembered" by the control system. How Parameter 1860 Works The Role of Parameter 1850 and 1860 :
In this article, we will focus on FANUC parameter 1860, also known as "1870 work" or "1870 function," which plays a vital role in the system's functionality. We will discuss what parameter 1860 is, its significance, and how to work with it.
: In an incremental setup, the machine hunts for a physical deceleration switch, drops its speed, and then registers the very next zero-marker pulse (grid) from the encoder. Parameter 1850 is applied here to shift the reference point relative to that marker pulse.
