(1)
It is recommended to use “ramp to stop” for safety of personnel or to prevent
material from being wasted in applications where the motor has to stop after the
drive is stopped. The deceleration time has to be set accordingly.
(2)
If motor free running is allowed or the load inertia is large, it is recommended to
select “coast to stop”. For example: blowers, punching machines, centrifuges
and pumps.
