L100 Inverter

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 particular applications.

Curve settings for acceleration and deceleration are independently selected. To enable the S-curve, use function A_97 (acceleration) and A_98 (deceleration).
