The Maximum Acceleration Jerk attribute value is used by motion instructions,
for example, MAM and MAJ, to determine the acceleration jerk to apply to the
axis when the acceleration jerk is specified as a percent of the Maximum. This
value is only used by an S-Curve profile.
Maximum Acceleration Jerk may be calculated in terms of a percent of
acceleration time spent while S-Curving.
In this case, 0 <= %time <= 100 %

The Maximum Deceleration Jerk attribute value is used by motion instructions,

axis when the deceleration jerk is specified as a percent of the Maximum. This
value is only used by an S-Curve profile.
Maximum Deceleration Jerk may be calculated in terms of a percent of
