Synchronized Stopping is a function that synchronizes the axes and stops the Servomotors
when an alarm occurs. Specifically, when an alarm occurs on either axis A or axis B, the syn-
chronized stopping axis is synchronized to the active alarm axis, and both Servomotors are
stopped together.
This function can prevent damage to the machine by synchronizing and stopping axis A and
axis B.
