Abstract
An embodiment of the present invention discloses an apparatus for recyclable absorption of electric retardation energy from a multiple axis industrial robotics system, including a robot control unit and at least one drive unit, which generates the electrical retardation energy at retardation. By an apparatus according to the present invention, the electric retardation energy, which occurs when a drive unit is retarded and is transferred into generator mode, may be recycled by the brake unit of the apparatus, which accelerates a mechanical device connected to the brake unit. The electric retardation energy is thus transferred into kinetic energy that may be stored in mechanical devices. An embodiment of the present invention also refers to a corresponding method for recyclable absorption of electric retardation energy from a multiple axis industrial robotics system.
