MOTOR DRIVE COMPONENT VERIFICATION SYSTEM AND METHOD
First Claim
1. A motor control system comprising:
- a plurality of monitored circuit components configured to cooperate to generate output signals for powering an electric motor;
memory circuitry configured to store reference identification data representative of circuit components that should be present, correct, communicating and operative in the system; and
processing circuitry coupled to the memory circuitry and configured to receive data from each of the monitored circuit components, to generate component identification data, and to compare the component identification data to the reference data to determine whether all monitored circuit components are present, correct, communicating and operative.

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.
