If the mechanics are smooth, the electrical drive system might be struggling to control the motor.
Servo Alarm Detection Threshold (Excessive Error) System: FANUC Series 16i / 18i / 21i / 30i / 31i / 32i (and equivalent 0i models) Category: Servo Parameter (Axis-Specific) fanuc parameter 1829
In a closed-loop CNC system, the controller constantly compares the (where the CNC tells the axis to go) with the Actual Position (where the encoder says the axis is). The difference is called the Position Error (or Following Error). If the mechanics are smooth, the electrical drive
In a CNC machine, when a motion command completes, the CNC expects the axis to settle exactly at the commanded position. However, factors like external forces or servo drift can cause a small difference between the commanded position and the actual position. This is called . In a CNC machine, when a motion command
An aggressively high gain setting forces the servo amplifier to constantly pump high current into the motor to correct tiny tracking errors. Over time, this strains the electrical components, leading to thermal overloads or instantaneous overcurrent alarms. Step-by-Step Procedure to Adjust Parameter 1829
