Abstract
A machine and control are provided for effecting motion of a function element, such as an adhesive material dispensing gun, and controlling the operation of the function element by means of a control signal proportional to the velocity of a workpoint associated with the function element. The control produces a velocity signal representing the velocity of the workpoint, calculates the value of a control signal using the velocity signal and predetermined constant defining the constant of proportionality and zero velocity output and applies the control signal to a digital-to-analogue converter to produce an output signal for controlling the function element.
