Trio Motion Technology

Coordinate transformations allow a machine to be programmed in a “Frame” which does not correspond one-to-one with the machine axes. An example of a very simple coordinate transform is given in the diagram. In this class of “single belt” machine, two stationary motors are used to produce X-Y motion. However if the motion required is in the Y direction both motors must move in opposite directions. For motion in the X direction the motors must move in the same direction. Frame transformations are commonly used with “robots” but can be useful in a much wider variety of machine types. A Motion Coordinator can have alternative “frames” installed which are dependant on the geometry of the machine being controlled. Some common transformations are available “off the shelf”. Alternatively for more unusual machines frame transformations can be easily added and linked to the standard Trio software using the ‘C’ language. Please contact your Trio distributor if you need to do this.
