The HLC Capacity Module Drive is manufactured by Rexroth, Indramat, Bosch.
These capacity module drives help to improve the energy balance in applications as well as in rapidly successive machining cycles. When one of these modules are hooked up to a DC bus, it then works as a power storage temporarily and also helps to reduces the loss of heat in the control cabinet because of the relief that it puts on the brake resistor. When a power failure occurs, the energy that has been stored lets a controlled return motion happen, which gives protection to the workpiece and the tools for gear cutting machines.
