SS2/SOS function

Outline
When SS2C (SS2 command) turns off, the SS2/SOS function executes stop monitoring (SOS) of the servo motor after
standby until a delay time set in advance is elapsed or until the servo motor stop is detected.
Sequence outline
The SS2/SOS function is activated by turning off SS2C (SS2 command).
Once the function is executed, it performs deceleration stop monitoring at first. Then, the function waits until the speed
reaches or falls below a certain point or until the specified time elapses. During this time, execute the deceleration command
from the controller. For details on speed monitoring and delay time monitoring during deceleration, refer to the following.
