Figure 6.6 DC Braking to Stop
DC Braking time is determined by b2-03 (DC Braking Time at Stop) and the output frequency
when a Stop command was entered.
DC Braking time = (b2-03)×10×Output frequency / d1-02(Maximum output frequency)

Note: If an OCD (Overcurrent) fault occurs, increase the minimum baseblock time to P2-01.
3 : Coast to Stop with Timer
When a Stop command is given, the drive shuts off its output and the motor will coast to stop.
The drive will ignore any Run command until the wait time (t) ends.
