Use % of Time for the Easiest Programming of Jerk
Use % of Time to specify how much of the acceleration or deceleration time has
jerk. You don’t have to calculate actual jerk values.
Example Profile
100% of Time At 100% of Time, the acceleration or deceleration changes the entire time that the axis speeds up or slows down.
60% of Time At 60% of Time, the acceleration or deceleration changes 60% of the time that the axis speeds up or slows down. The
acceleration or deceleration is constant for the other 40%.
