Accel/Decel
Characteristics
Standard (default) acceleration and deceleration is linear with time. The inverter CPU can also
calculate other curves shown in the graphs below. The sigmoid, U-shape, and reverse U-shape
curves are useful for favoring the load characteristics in particular applications. Curve settings
for acceleration and deceleration are independently selected parameters A097 and A098
respectively. You can use the same or different curve types for acceleration and deceleration.
