You can select the dynamic brake as a method to stop the Servomotor when the Servo is turned OFF
(PDS state machine = Disable operation). Also, you can select the dynamic brake for the operation
after stopping.
Use the Stop Selection - Disable Operation Option Code (3B20-02 hex) for setting.
You can select the dynamic brake as a method to stop the Servomotor when an error occurs (PDS state
= Fault reaction active). Also, you can select the dynamic brake for the operation after stopping.
Use the Stop Selection - Fault Reaction Option Code (3B20-04 hex) for setting.

when the P-N Voltage drops to the specified value or lower. In other cases, the Servomotor
decelerates to stop according to the setting of Operation A.
