Most standard Fanuc motors use rotary encoders. The parameter is often related to the number of pulses per revolution and the ball screw pitch.
: Cycle the power to the machine entirely (turn off, wait 10 seconds, turn on). Verify : Check that the machine position displays correctly. Conclusion
When changing a servo motor, the value in 1860 must match the encoder's required pulses to ensure the machine accurately recalls its position after a power-off. fanuc parameter 1860 work
Note: This parameter interacts with Parameter 1821 (Detected Unit/CMR). If 1821 is set incorrectly, 1860 will not solve the issue.
Understanding Fanuc Parameter 1860: Absolute Position Work Settings Most standard Fanuc motors use rotary encoders
In the FANUC Series 30i, 31i, and 32i (as well as 16i, 18i, and 21i) CNC systems, (APZ) is a crucial bit-type parameter used to establish and indicate the Absolute Position for each axis when utilizing absolute pulse coders . Feature & Functionality
Re-navigate to the setting screen and switch . Verify : Check that the machine position displays correctly
For a machine tool builder or maintenance technician, correctly configuring Parameter 1860 is a non-negotiable step during initial commissioning or after replacing a servo motor or coder.
