Abstract
A technique is provided for verifying the proper selection, installation, communication and operability of components in power electronic systems, such as motor drives. A processing circuit is coupled to multiple components or subsystems that identify themselves to the processing system. An identification code is stored that is compared to a similar code built based upon the information reported by the components at the time of commissioning, operation or servicing. If the comparison indicates that all components are properly installed, and communicating and operative, operation may continue. The technique may be applied in parallel motor drives at a power layer level to allow separate and parallel verification of component and component operation in the parallel drives.
