What is Multi-Axis control?
A complete description of a vibration environment involves simultaneous motion in more than one direction. In fact, the most general description of motion of a body at a point in space, involves 6 independently specified motions (called mechanical Degrees of Freedom, DOF): X, Y, Z, ThetaX, ThetaY and ThetaZ. A full road simulation of a vehicle involves 6 DOF excitation at each wheel.
