Use the directional cursor keys to highlight the specific axis you need to modify. Type the new value in detection units using the keypad. Press the softkey to save the change. Repeat for any other axes if necessary. Step 4: Clear the PWE Alarm Press the [OFFSET/SETTING] key again. Change PARAMETER WRITE (PWE) back from 1 to 0 . Press the [RESET] key to clear the flashing P/S 100 alarm.
The primary role of Parameter 1860 is to hold the coordinate value that aligns the machine's physical position with the feedback from the absolute encoder.
When executing a coordinate calibration or recovering from an absolute pulse coder battery failure, Parameter 1860 bridges the gap between the machine's absolute electrical grid and its actual physical alignment. Parameter Technical Overview : 1860 Data Type : Two-word axis (Long Integer) Valid Range : -99999999 to 99999999 Default Value : 0 fanuc parameter 1860 full
It defines the amount of offset added to the velocity command immediately following a reversal in axis direction to compensate for mechanical backlash. Typical Setting Range: 20 to 600. Related Parameters:
Fanuc Parameter 1860 is defined as the . Use the directional cursor keys to highlight the
In the world of high-precision CNC machining, the occupies a unique and somewhat mysterious position. While many common parameters like 1851 (backlash compensation) are frequently adjusted by technicians, Parameter 1860 is often described as an "untouchable" or "read-only" value that provides a fascinating look into the machine's internal logic. The Digital Pulse: What is Parameter 1860?
While you cannot "manually" set Parameter 1860 to a specific number to fix a machine, observing it is a powerful diagnostic tool. Repeat for any other axes if necessary
Before making changes, perform a full parameter backup to an SRAM card or USB stick.
: It is typically a 2-word (long integer) axis-specific parameter.
) is vital for complex multi-axis milling, turning, and profiling. Parameter 1860 works closely with Parameter 1815 and Parameter 1861 to dictate exactly how and when the CNC system refreshes its reference position calculation relative to physical coordinates.
