Product Description:

The EFC5610-37K0-3P4-MDA-7P-SVPNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat and supplied within the EFC 5610 segment of the EFC Frequency Converters series. The unit converts a fixed utility supply into a variable output frequency so that industrial AC motors can follow process demands in automated machinery. By replacing mechanical throttling devices, it improves energy efficiency while maintaining precise speed and torque for conveyor, pump, and fan applications. It is suited to applications where gradual starts and controlled acceleration are preferred over direct-on-line motor operation.

Internally, the converter is engineered for heavy-duty operation on a nominal supply of 400 V, accepting fluctuations between 380 and 480 V. It connects to a three-phase network and can deliver up to 37.0 kW of motor output in heavy-duty service. Motion is regulated by Standard Vector control SVC, providing accurate torque and speed control without an external encoder. The device uses a standard control configuration with Flex-Control architecture and standard I/O for discrete signal integration. A standard LCD display with a potentiometer on the front panel permits local parameter entry and speed trimming, which is useful when direct access at the cabinet is needed. The unit carries an IP20 protection class, so it must be installed inside a ventilated electrical cabinet.

The communication layer uses Modbus, allowing the drive to exchange setpoints and diagnostic words with PLCs over a simple serial link. An integrated EMC filter rated for industrial-area class C3 helps the installation meet conducted-emission limits when long motor cables are present. For personnel protection, the built-in safety function is Safe Torque Off (STO), which removes drive energy without engaging mechanical brakes. The unit uses frame size H, which gives it a consistent mounting footprint within this drive range. This cabinet-friendly form helps it fit control panels where space, airflow, and cable routing need to stay organized.
