A servo motor's built-in temperature sensor tripped. The motor is too hot, or the sensor or its wiring has failed.
Axis overloaded by binding, heavy cuts or a counterbalance problem. Brake dragging on a vertical axis. Motor cooling blocked by chips or sludge. Failed thermal sensor or encoder.
Let the machine cool down and see if the alarm clears. Feel the motor (carefully) and compare with the other axes. Check the load meter while jogging the axis. Clean chips and coolant sludge off the motor. If it comes back after cooling, or the motor is hot while the load looks normal, have a tech check the brake, the motor and its feedback.
