US Patent 7146470 Real-time motor controller with additional down-up-loadable controller functionality

A controller, in particular a drive controller, includes a first functional block for at least one permanently installed controller function and a second functional block for at least one dynamically loadable controller function. The second functional block can be dynamically loaded and/or dynamically overwritten as well as started and/or executed while the controller is operating, without affecting the operation of the controller. During the operation of the controller, an additional function that is only temporarily required, can be loaded as needed, or an already loaded, but only temporarily required additional function can be dynamically loaded or overwritten by another temporarily required additional function.
