Allow the motor to coast to a stop when the run
command is turned OFF in order to minimize
the variation of deceleration torque.
Coast-to-stop
Allow the motor to coast to a stop in order to
prevent conflict with the mechanical brake.

S-curve
acceleration/dec
eleration
Apply S-curve to the acceleration/deceleration
pattern to gradually accelerate/decelerate the
motor to reduce an impact that
acceleration/deceleration would make on the
machinery.
