B&R Industrial Automation: Optimal drive sizing reduces energy consumption
B&R ensures that drives can be sized in a targeted manner using the SERVOsoft tool from ControlEng.
The masses to be moved and the drives needed to do it can be precisely matched, which reduces energy consumption. For complex machines where movements are executed consecutively, kinetic energy is often released in the braking resistors in the form of heat. By connecting ACOPOSmulti servo drives via the DC bus, up to 30% of the energy used for movements are said to be saved. Brake energy is stored in capacitors and made available at a later time for acceleration. A cooler control cabinet is possible because the heat from the resistors is greatly reduced.
