There is no universal value. The correct setting depends on your workflow:
Pro technique: Use FANUC’s #8000 series system variables to query the current search status dynamically—though not directly settable via macro, you can detect search failures and retry with a higher range. fanuc parameter 1829
Parameter Number: 1829
Full Name: Servo Software Stroke Limit 2 (Positive Direction)
Control Type: FANUC Series 0i, 30i/31i/32i, 16i/18i/21i, and similar CNC models. There is no universal value
Parameter 1829 defines the second positive software overtravel limit for servo axes. It works in conjunction with Parameter 1828 (first positive limit) to provide a multi-stage safety boundary for axis movement. Pro technique: Use FANUC’s #8000 series system variables
There is no universal "best" value. The correct setting depends on your machine's mechanics, tuning, and maximum rapid feedrate. Use this formula:
Parameter 1829 (min value) = (Max Rapid Feedrate / 60 / Parameter 1825) * Safety Factor (1.5 to 2.5)
