 Ramp to stop: the AC motor drive decelerates to 0 or the minimum output frequency according
to the set deceleration time, and then to stop (according to Pr.01-07).
 Coast to stop: the AC motor drive stops output immediately, and the motor coasts to stop
according to the load inertia.
(1) Use "ramp to stop" for the safety of personnel, or to prevent material from being wasted in
applications where the motor must stop immediately after the drive stops. You must set the
deceleration time accordingly.
(2) If idling is allowed, or the load inertia is large, use "coast to stop". For example, blowers,
punching machines and pumps
