Product Description:

The EFC5610-3K00-3P4-MDA-NN-NNNNN-L1NN frequency converter is produced by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. As a variable-speed drive component, it modulates the supply to three-phase induction motors. This allows conveyor lines, pumps, or fan stages to be matched precisely to process requirements in industrial automation.

It accepts a mains input of 400 V AC, and the permitted window from 380 to 480 V accommodates common factory power grids subject to ±10% fluctuation. Internally, the converter is wired for three phases, so it can deliver balanced output currents without creating a neutral shift. Process control data can be issued through Modbus, enabling direct integration with PLCs that follow this open serial protocol. This communication path allows higher-level controllers to send operating commands and read drive status over a standard serial link. Motor flux is handled through standard vector control SVC, which maintains torque at low speeds by regulating phase current and voltage in real time. This control method improves low-speed response compared with basic volts-per-hertz operation. Mechanical accommodation is helped by its frame size D, matching the mounting pattern used for other devices in the 22 cm height class.

The heavy-duty rating supports a motor shaft output of 3.0 kW, which is suitable for medium conveyors or cooling tower fans driven from the EFC 5610 control section. Protection against accidental contact is provided by the IP20 housing, and safety logic is extended with Safe Torque Off (STO), which disconnects gate firing almost instantaneously when an emergency stop circuit opens. The built-in filter is rated for industrial area, class C3 and reduces conducted radio interference, making additional external EMC hardware unnecessary in most installations. A dust cover replaces the local keypad because this unit does not include a display panel. Flex-Control standard I/O and the standard control configuration provide digital and analog terminals for speed reference, fault reset, and process feedback.
