S-Curve Acceleration/Deceleration
A S-Curve pattern is used to reduce shock and provide smooth transitions during machine
acceleration and deceleration. S-Curve characteristic time is the time from the output frequency to
the set accel/decel time. See S-Curve Characteristic timing diagrams below and on the following
page.
The figure below shows FWD/REV run switching during deceleration to stop. The S-curve function
will add time to the acceleration and deceleration. Time to accelerate from the minimum frequency
to the maximum frequency (total acceleration) = B5-01 + (D9-01 + D9-02)/2.
