Abstract
A system and method in accordance with the present technique for protecting motor drives from damage due to misconfiguration while coupled to a common DC bus, comprises sensing electrical operating parameters of the motor drives, automatically determining whether each of the drives is actually installed as a common bus leader or a common bus follower, and comparing the actual installation of the motor drives to a respective stored configuration of each of the motor drives as either a common bus leader or a common bus follower.
