Description
Defines the shape of the acceleration ramp at the beginning
of the acceleration.
0.000 s: Linear ramp. Suitable for steady acceleration or
deceleration and for slow ramps.
0.001...1000.000 s: S-curve ramp. S-curve ramps are ideal
for lifting applications. The S-curve consists of symmetrical
curves at both ends of the ramp and a linear part in between.

Ramp shape at start of acceleration.
Defines the shape of the acceleration ramp at the end of the
acceleration. See parameter
Ramp shape at end of acceleration.
Defines the shape of the deceleration ramp at the beginning
of the deceleration. See parameter
