Note: The YInverseSinusoid motionlaw is usually applied to a rotating part, e.g. a Crank. There can be only one YInverseSinusoid segment in each motion.
The ConstantVelocity Inverse Crank is a similar motionlaw. There can be more than ConstantVelocity Inverse Crank one segment in each motion.

YInverse Sinusoid 

Example: with two segments. Crank rotates in a CounterClockwise direction ConstantVelocity Starts at 50mm to Left of CrankCenter (angle 120º) ConstantVelocity Ends at 50 to Right of CrankCenter (angle 60º) Segment 1: •Xaxis Start = 0 ; End = 90º The Y–Inverse Sinusoid SegmentParameters are: •Radius of Rocker = 100mm, Start Position = 50, End Position = 50mm. With these SegmentParameters: •The Y–axis is 120º†, when the Master Machine Angle (MMA) is 0º . •The Y–axis is 60º, when the Master Machine Angle is 90º . Segment 2: •Xaxis Start = 90º, End = 360º (0º) A FlexiblePolynomial •The Y–axis is 60º, when the Master Machine Angle is 90º (= end of Segment 1) •The Y–axis –240º when the Master Machine Angle is 360º . Thus the Crank makes a full rotation from +120 to 240 in a counterclockwise direction.
