Uses the dynamic brake to stop the Servomotor, and
cancels dynamic brake status after stopping to go into
coast status.

Coasts the Servomotor to a stop. The Servomotor is
turned OFF and stops due to equipment friction.
Note
If the Servomotor is stopped or rotating at extremely low speed when the items
above are set at 0 (dynamic brake status after stopping with the dynamic brake),
then braking power is not generated and the Servomotor will stop the same as
in coast status.
