S-Curve Acceleration/Deceleration
An 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.
Figure 5-23 shows FWD/REV run switching during deceleration to stop. The S-Curve function will
add time to the acceleration and deceleration.
Total time to acceleration from minimum frequency to maximum frequency (total acceleration) is:
Total time to deceleration from maximum frequency to minimum frequency (total deceleration) is:
