 Ramp to stop: the AC motor drive decelerates from the setting of deceleration time to 0 or
minimum output frequency (Pr. 01-09) and then stop (by Pr.01-07).
 Coast to stop: the AC motor drive stops the output instantly upon a STOP command and the
motor free runs until it comes to a complete standstill.
(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 the motor free running is allowed or the load inertia is large, it is recommended to select
"coast to stop". For example, blowers, punching machines and pumps
 The stop method of the torque control is also set by Pr.00-22.
