④During normal forward/reverse run(＝)：
Not recognized as a stop command, so that DC injection braking is not active.
⑤If 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.

・Function
This function is useful for preventing the motor shaft from rotating freely or for
preheating the motor.
