This is the most serious consequence. You calculated the shift in the wrong direction. Always test with a dry run and the rapid override turned to 25% or lower.
WARNING: Changing servo parameters can cause axis runaways or crashes. Clear the machine work zone and be prepared to hit E-STOP immediately. fanuc parameter 1860 full
This is not an error, but a reminder. Set PWE back to 0. This is the most serious consequence
There is no universal "perfect" number for 1860. It depends on your machine's mechanical design, motor torque, and the workpiece material. However, you can calculate a safe starting point. WARNING: Changing servo parameters can cause axis runaways
Machine: Vertical mill with βiA encoder (8000 pulses/rev).
Parameter 1820 = 8000 (no division).
1860 should be = 8000 ÷ 8000 = 1.
If 1860 = 2, then counter capacity = 4000 pulses. The CNC will think one motor rev = 4000 pulses, causing the reference point to occur twice per physical motor revolution → unstable grid.
