Zusammenfassung:	A method of operating an implantable blood pump including connecting the implantable blood pump to a primary controller, the primary controller being configured to operate the implantable blood pump, and a secondary controller. The secondary controller synchronizes its own motor drive signals to a frequency and phase of the primary controller's motor drive signals, without actively contributing power to the implantable blood pump. An imminent or actual disconnection event is detected in which the primary controller is disconnected from the implantable blood pump. Uninterrupted operation of the implantable blood pump is continued with the secondary controller.
