How is the velocity, acceleration and jerk calculated?
see also: FAQs MotionDesigner has the mathematical expressions for each of the segment types at each derivative explicitly given within the code. The following information is required by MotionDesigner to plug in to the explicit expression of position, velocity, acceleration and jerk: Segment Width Cycles per Minute, Segment Type, and the Segment Blend-Point Values NB: Even if you design a motion that is more or less than 360 degrees, the cycle time will assume a total of 360 degrees. For example, if a width of 60 degrees is set in the width data field, and the machine is set at 90 cycles per minute, then the segment duration for the purposes of calculating velocity, acceleration and jerk is. Segment Width = 60 (degrees) * 1/360 (cycles/degree) * 1/90 (minutes/cycle) * 60 (seconds/minute) Segment Width = 111.1msec.
