What does "Servo Motor Overtemp" mean?
Hello,
What does servo motor overtemp mean in layman's terms? Can someone provide a basic explanation or definition of a servo motor overtemp message and its possible causes. Thank you!

hat is servo motor overtemp?
Servo motor overtemp is obviously caused by excessive temprature in a servo motor. It can be sensed by an internal thermistor circuit within the motor windings or some form of external temperature sensor.
Servo motor overtemp is directly related to high current in one or more of the motor windings. There are few things to look for...
- Servo motor overtemp can be caused by breakdown of one or more motor windings
- Servo motor overtemp can be caused by excessive loading of the motor
- Servo motor overtemp can be caused by improper motor tuning, for instance, too much gain
- Overtemp alrams can also be caused by a faulty temperature sensing circuit (ie bad thermistor or thermocouple)
Servo motor overtemp alarms never have a good ending if the problem isn't resolved. You'll see component breakdown not far behind. I think of servo motor overtemp alarms as a wakeup call that you are about to experience a failure.
