Especially for gantry systems, rapidly accelerating heavy loads can shoot the electrical power demand of frequency drives through the roof. At the same time while braking, regenerative energy is being put back into the drive system. For Ilsemann Automation, the challenge was to make the most effective use of the braking energy and to not dissipate it in braking resistors. In its retrieval robots for plastic processors, the company uses a drive solution from SEW-EURODRIVE that minimizes energy consumption, while at the same time boosting the operational reliability of the system.
