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.
