The Hitachi VFD's features two-stage accelera�on and decelera�on ramps. This gives flexibility in the profile shape while running in
the infinite variable method. This feature allows you to have more control in the accel and decel while transi�oning your frequency.
You can specify the frequency transi�on point, the point at which the standard accelera�on (AC120) or decelera�on (AC122)
changes to the second accelera�on (AC124) or decelera�on (AC126).
Use the table below to configure the 2-Stage Accel & Decel feature.
