In various forms, the modular motor control system may comprise one or more motor controllers each having an associated motor. The one or more motor controllers may be in communication with a master controller. The master controller is configured to provide control signals to the motor controllers to control the associated motors. In some forms, the one or more motor controllers and the associated motors may be located within a surgical module. The surgical module may provide a communications interface between the master controller and the one or more motor controllers.
