With the Energy Saving Module (ESM), Kollmorgen provides a capacitor module that, in combination with the servo-amplifier, can store energy when decelerating and subsequently use it for acceleration. As a result, machines that leverage the modume consume less energy and operate more reliably in regions or company networks that suffer from irregular power supplies. The new solution also allows all axes to be driven in a defined preferred position in the event of a network failure, eliminating accidents and expensive repairs. The module can reduce overall operating costs, with a corresponding rise in safety, productivity and manufacturing quality, enabling machine engineers and users to improve their competitive position. With the product, energy that is converted into heat through conventional technology with brake resistance remains in the system and can be used at a later point in time. This contributes to lower energy consumption and reduced energy costs. In printing and packaging applications, for instance, up to 70% of energy can be saved, where acceleration and braking occur continually. Additional benefits associated with lower energy requirements include considerably lower CO2 pollution, the option of operating more machines with a given power supply, plus reduced ambient heat in the switching cabinet. In addition, by storing otherwise wasted energy the ESM can bridge the power gap in the event of short power voltage dips and power cuts. This is significant in fast and complex applications in particular, as moving parts whose paths cross could otherwise collide if the energy supply is interrupted. Such accidents can result in lengthy and costly repairs, and reduced productivity. An additional advantage is that, as the module evens out instabilities in the power supply, it can contribute to higher manufacturing quality. This is particularly significant in time-consuming applications such as grinding lenses, milling motor blocks or calibrating telescopes, where power dips can result in errors.
