Post: Fanuc Parameter 1860 — What it is and how to use it
Parameter 1860 on Fanuc controls the spindle override low-speed limit (minimum spindle speed allowed when using the spindle override). Set and use it carefully — incorrect values can lead to poor machining or damage.
Fanuc Parameter 1860 stores the current position data of the absolute pulse coder (APC) for each axis. fanuc parameter 1860
If the machine's physical home position needs to be shifted (e.g., after a crash or maintenance), technicians may manually adjust the value in 1860 or perform a new zero-set sequence to overwrite it. en.industryarena.com Safety Warning Post: Fanuc Parameter 1860 — What it is
: The value in 1860 often uses modular arithmetic, meaning the count "wraps around" once it reaches a certain limit based on the encoder's resolution. Relationship to Zeroing You have the correct documentation for your specific
Unlike incremental encoders that require a homing sequence (zero return) every time the machine is powered up, an absolute encoder remembers its position. Parameter 1860 holds this numerical value for each controlled axis. System Correspondence:
- You have the correct documentation for your specific FANUC CNC system and I/O device.
- You understand the I/O device's configuration and communication requirements.
- You set the correct value to avoid any potential communication errors or system malfunction.
