The Acceleration Time is used to determine the time required for the AC motor drive to ramp
from 0Hz to Maximum Output Frequency (Pr.01-00).
The Deceleration Time is used to determine the time require for the AC motor drive to
decelerate from the Maximum Output Frequency (Pr.01-00) down to 0Hz.
The Acceleration/Deceleration Time 1, 2, 3, 4 are selected according to the Multi-function Input
Terminals settings. The factory settings are acceleration time 1 and deceleration time 1.
The larger against torque and inertia torque of the load and the accel./decel. time setting is
less than the necessary value, it will enable torque limit and stall prevention function. When it
happens, actual accel./decel. time will be longer than the action above.
