What is PVAJT Motion

PVAJT motion is a lot more complicated to use because it requires an array of Positions, Velocities, Acceleration, Jerk, and Time deltas. The controller is not responsible for figuring out anything because it streams the arrays straight to the frame buffer. This makes it very flexible and gives users absolute control over the motion path. The controller does not do any interpolation or calculations because everything it needs is calculated beforehand in the PVAJT arrays.


Output Example

PVAJT is useful if you must control the acceleration and jerk percent profile throughout motion.

The example to the right shows a 50% jerk SCurve trapezoidal move. This move requires 7 elements in each array. One segment for each rising/constant/falling segment of the acceleration profile.

The math for PVAJT can be very cumbersome. We recommend you explore all other motion types before trying to implement this method.

Note: The Position, Velocity, Acceleration, and Jerk arrays are all direction sensitive meaning you must put a (-) sign on negative numbers.
