detected within the servo system. This alarm typically triggers when a temperature sensor in the encoder or the servo amplifier identifies that operating temperatures have exceeded safe limits. Tri Star CNC Services Core Meanings and Causes Encoder/Motor Overheat

Not always. However, it does indicate a problem with the motor's internal encoder, which is not a field-serviceable part for most maintenance teams (requiring a cleanroom for alignment). While you can try cleaning the encoder's internal glass disk, in high-production environments, swapping the entire motor is the most common and cost-effective solution.

Ignoring this alarm can lead to scrapped parts, position drift, and potentially dangerous random axis movements. Diagnosing it requires a systematic approach—checking parameters, cables, motors, and the mechanical drivetrain for feedback interference or failure.
Always perform a full power cycle after changing servo parameters to ensure they take effect.
