The EFC 3610 and EFC 5610 frequency converters from Rexroth address energy-consumption issues facing operators of high-capacity pumps, compressors and fans. Scalable in performance and functionality features, the units can be integrated into a wide range of automation environments with simple commissioning and open interfaces.
These intelligent frequency converters control machine speed as demanded, potentially significantly reducing energy consumption. Featuring a removable operator display panel, the devices allow simple commissioning without need of external programming devices or a PC—the user can auto-tune and enter, change or backup parameters. Digital inputs/outputs make simple direct coupling with a PLC possible. Assembly is significantly reduced by time-saving installation technology using plug-in terminals and an attachment option on standard DIN rail. The EFC3610 series cover the power range from 0.4 to 22 kW or 0.5 to 30 hp, while the EFC5610 provides an expanded range up to 90 kW or 125 hp and safe torque off (STO). In addition to the freely definable V/f (V/Hz) operation, the EFC 5610 also offers vector control for an optimal torque curve.
