If the auto accel/decel is selected, the AC drive will accel/ decel in the fastest and
smoothest means possible by automatically adjusting the time of accel/decel.

These two parameters allow you to configure whether the acceleration and/or
deceleration ramps are linear or S-shaped. The S-curve is enabled when set at
d1-d7. Setting d1 offers the quickest S-curve and d7 offers the longest and
smoothest S-curve. The AC drive will not follow the accel/decel time in Pr.1-09 to
Pr.1-12. To Disable the S-curve, set Pr.1-16 and Pr.1-17 to d0.
