MOTOR DRIVE SYNCHRONIZATION SYSTEM AND METHOD

摘要

Multiple motor drives are synchronized to permit complex coordination in operation. Each motor drive includes a control circuit coupled to functional circuits that are separately supported and linked to the control circuit via dedicated serial interfaces. The control circuit generates interrupts for coordinated transfer and collection of data from all functional circuits. Each drive includes a synchronization counter, and all synchronization counters are linked via a network link. The synchronization counters synchronized clocks of each control circuit. The interrupts, and consequent data transfer and collection are thus synchronized between all drives based on the synchronization of the clocks.
