2) Alarm List

Operation at detecting: "DB" performs the slowdown stop of the servo motor in dynamic brake operation when the alarm generating. Operation at detecting: "SB"
performs the slowdown stop of the servo motor with sequence current limiting value.
When dynamic brake is selected by Emergency Stop Operation selection, the servo motor is decelerating stopped for the dynamic brake operation regardless of
the operation when detecting it. (However, it stops in free servo brake operation at the time of alarm 53H (DB resistor overheating) detection.
* Note that servo amplifier without dynamic brake function stopps in free-running.
