Accel/Decel

Standard acceleration and deceleration is
linear. The inverter CPU can also
calculate an S-curve acceleration or
deceleration curve as shown. This profile
is useful
characteristics in particular applications.
Curve settings for acceleration and
deceleration are independently selected.
To enable the S-curve, use function A097
(acceleration) and A098 (deceleration).
