Product Description:

The EFC5610-7K50-3P4-MDA-NN-NNNNN-L1NN frequency converter is produced by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. It functions as an AC-to-AC inverter that varies output frequency and voltage so three-phase induction motors can run at the speed demanded by pumps, fans, conveyors, or similar automated loads. This control method helps the connected motor match process demand more closely than fixed-speed operation. Classified in product line 02 and the EFC 5610 model group, the unit provides a consistent footprint and parameter structure across multiple power ratings for distributed drive systems.

The converter accepts a mains supply of 400 V AC and supports an input range of 380 to 480 V, allowing direct connection to common plant power without external transformers. Internally it uses standard vector control (SVC) to keep torque available at low speed while responding quickly to load changes. The heavy-duty rating supports motors up to 7.5 kW, which suits medium conveyor sections and process pumps. Power is processed through a three-phase input bridge, helping balance line currents and reduce stress on the supply. Parameter access, status words, and remote commands are exchanged through Modbus, so the drive can communicate with standard PLC registers without additional gateways.

The housing follows Frame Size E, which sets the standard height, width, depth, and mounting hole pattern used for panel installation. Control electronics use the Flex-Control with Standard I/O layout, providing six digital inputs, two analog channels, and a relay output for standalone logic or sequencer tasks. An integrated Safe Torque Off (STO) circuit removes firing pulses to the IGBTs when an emergency input is triggered, preventing the motor from producing mechanical energy. The enclosure carries an IP 20 protection class, so the unit is intended for installation inside a clean control cabinet. Its C3 industrial EMC filter helps limit conducted emissions in factory environments.
