A faulty servo drive may not be providing enough torque to maintain the position, leading to deviation.
: Detection unit (typically microns or pulses, depending on your machine's resolution).
Particularly on vertical axes, if the Z-axis mechanical brake fails to hold the motor, the axis will drop, causing a massive deviation.
When a FANUC system triggers an excessive stopping error alarm, the root cause can fall into several categories. Understanding these will help you troubleshoot effectively before resorting to parameter adjustments. fanuc parameter 1829
If you are seeing an alarm related to this parameter, check the following:
Have you already performed a or used a dial indicator?
Set "Parameter Write Enable" to 1 in the SETTING screen. A faulty servo drive may not be providing
The relationship between these parameters is interconnected. For example, excessive following error during movement (Parameter 1828 violation) may lead to overshoot after stopping, potentially triggering Parameter 1829 as well. Conversely, improper loop gain settings (Parameter 1825) can cause instability that manifests as stopping errors.
Causes "clunking" sounds or visible "pitting" at reversal points.
In simple terms, sets the maximum allowable torque (or current) for the servo motor during operation. When a FANUC system triggers an excessive stopping
: The axis hesitates slightly during direction changes, resulting in parts that are out-of-round.
What of Fanuc control are you using (e.g., 0i-TD, 31i)?
