Fanuc Parameter 1829 Page

Increased Parameter 1829 to 30,000 . Alarm gone. No mechanical issue – the factory parameter was simply incorrect for the machine's rapid speed.

If the servo gain is too low, the motor might "drift" too far from its target position. Troubleshooting and Adjustments fanuc parameter 1829

Think of it as the "vibe check" the controller performs while the machine is supposed to be sitting still. When an axis isn't moving, the CNC expects it to stay exactly where it is. However, due to gravity, mechanical friction, or a worn-out ballscrew, that axis might sag or drift. Parameter 1829 sets the maximum "slack" (positional deviation) the machine will tolerate before it panics and throws an alarm . The "Story" of Parameter 1829: When Silence Isn't Still Increased Parameter 1829 to 30,000

: If the deviation exceeds the value set in 1829, the CNC triggers a 410 Servo Alarm ("Excess Error Stop"). If the servo gain is too low, the
