01 - 16 Acceleration S-Curve
01 - 17 Deceleration S-Curve
Factory Setting: 00
Settings 00 S-curve disabled
01 to 07 S-curve enabled (07 is the smoothest)
 This parameter is used to ensure smooth acceleration and deceleration via S-curve.
The S-curve is disabled when set to 00 and enabled when set to 01 to 07.
Setting 01 gives the quickest and setting 07 the longest and smoothest S-curve.
 The diagram below shows that the original setting of the Accel/Decel Time is only for reference
when the S-curve is enabled. The actual Accel/Decel Time depends on the selected S-curve
(01 to 07).
