ACC/DEC time is the time taken to accelerate from 0 r/min to the rated (3000 r/min by default)
speed in the given command or decelerates from the rated speed to 0 r/min. If the given speed is
not equal to the rated speed, the actual ACC/DEC time is the set ACC/DEC time multiplied by the
ratio of the given speed to the rated speed. If the speed command is negative, the absolute value
is used to calculate the ACC/DEC time.
Example: If the given speed is 2000 r/min, the rated speed is 3000 r/min, and the ACC/DEC time
(P0.54/P0.55) is set to 1500, then the actual ACC time t1 is 1500×(2000/3000)=1000ms and the
DEC time t2 is 1500×(2000/3000)=1000ms. See the following figure:
