Not recognized as a stop command, so that DC injection braking is not active.
If a reverse run (or forward) command is entered during forward run (or reverse)
( ) DC injection braking starts when the frequency set with  exceeds the
reference frequency during deceleration.
If an operation command is entered during D.C. braking priority is given to D.C. braking.
