Abstract
A system and method is disclosed for intelligent power management of actuators such as those used in papermaking. Multiple power supply units are connected to a common power bus. The power bus is connected at predetermined locations to a communications bus. The communications bus is connected in series with all of the actuators. The actuators are arranged in predetermined groups. A computing device determines if electrical power can be supplied to some or all of the actuators that are requesting simultaneous movement and if there is insufficient power for all such actuators the computing device issues permission for actuators to move based on a preselected criteria.
