After STOP reference received, the AC motor drive shall control the motor to stop as parameter set.
Deceleration and stop: according to deceleration time set by 1-10 or 1-12, AC motor drive
decelerate in tape speed way to min output frequency(1-05) and then machine stops.
Coast to a stop: AC motor drive stops output immediately and motor runs freely in load inertia and
then stops.
1 Deceleration and stops 2. Free running
The motor stopping mode depends on the characteristics of load or machinery stopping
It’s recommended to choose the mode of deceleration and stop in circumstance that, when
machines stops, motor shall stop immediately to avoid individual injury or waste of materials.
However, deceleration time shall be determined according to specific characteristics of machine.
While it shall be set to free running and stops, provided motor idling allowable or machine with large
load flexibility, for example, air fan, pump and stirring machines.
