Abstract
A method for resolving addressing conflicts between multiple electronically commutated motors communicatively coupled to a system controller is described. The method includes sending a command, from the system controller, to an address and determining, based on responses or lack of a response received at the system controller, a status of the address. The method further includes repeating the sending and determining steps to determine which addresses are not used and which addresses indicate existence of an addressing conflict and sending messages from the system controller to reassign the addresses of at least one of the plurality of motors to an unused address if the status indicates one or more of the addresses have a conflict.
