Without a correctly configured Parameter 1860, the CNC system would lose its "memory" of where the tools and workpieces are located relative to the machine bed. This parameter ensures that even if the machine is turned off for extended periods, it resumes operation with high precision, maintaining the integrity of the work coordinate systems and preventing potential mechanical crashes.

If there is a mismatch between the physical position of the tool and what the screen shows, technicians may verify the value in 1860 to ensure the absolute pulse coder is communicating correctly. Troubleshooting Alarms: Alarms like APC Alarm 300 Mastering FANUC Parameter 1860: How It Works and
Note: This parameter interacts with Parameter 1821 (Detected Unit/CMR). If 1821 is set incorrectly, 1860 will not solve the issue. Troubleshooting Alarms: Alarms like APC Alarm 300 Note:
