Deceleration Stop: Timing for Engaging Brake (No.232.3) = 0
*1) MBRK turns OFF is when one of the following becomes true, a) Deceleration Stop completes, or b) Motor rotational speed drops to
the value of [Deceleration stop - Rotational speed to cancel (No.227.0)] or below.
*2) If the deceleration stop method is quick stop, the motor will remain excited during deceleration stop.

*1) MBRK turns OFF is when one of the following becomes true, a) Deceleration Stop completes, or b) Motor rotational speed, after the time
specified by Parameter No.234.0 elapses, drops to the value specified by Parameter No.235.0 or below.
*2) If the deceleration stop method is quick stop, the motor will remain excited during deceleration stop.
