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 for
favoring the load characteristics in particu-
lar applications.
Curve settings for acceleration and decel-
eration are independently selected. To
enable the S-curve, use function A097
(acceleration) and A098 (deceleration).
