Product Description:

The EFC5610-90K0-3P4-MDA-7P-DRNNN-L1NN frequency converter is produced by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. The unit is intended for panel mounting inside machine cabinets, where it varies the output frequency applied to squirrel-cage motors to provide speed and torque regulation for conveyors, pumps, and general-purpose automation tasks. Its Flex-Control electronics support standard I/O for integration with PLCs and other cabinet controls. By adjusting motor output to match process demand, the converter supports smoother starts and more stable operation during routine industrial use.

The drive uses standard vector control SVC, a control method that regulates magnetic flux and motor current in real time to maintain stable torque through the speed range. The permitted supply window is 400 V (AC 380…480 V -15% / +10%), so the converter can be connected directly to common plant mains without an autotransformer. In heavy-duty mode, it delivers 90.0 kW to the motor, which suits applications with high breakaway or overload demand. Its housing carries an IP20 protection class, indicating finger-safe openings and the need for installation inside a clean electrical enclosure. For functional safety, the integrated Safe Torque Off (STO) input removes inverter pulses quickly, allowing the mechanical system to coast without uncontrolled motor torque.

System communication is handled through Modbus, enabling parameter access, status monitoring, and serial integration without additional option cards. To reduce conducted emissions, the standard power stage includes an industrial area, class C3 EMC filter, so external line chokes are typically only considered when motor cables are long. The converter is built on the compact J frame, which helps conserve cabinet space while accommodating the internal power section. It is intended for a three-phase input system, matching common industrial power distribution used for larger motor drives.
