Product Description:

The EFC5610-30K0-3P4-MDA-7P-DRNNN-L1NN frequency converter manufactured by Bosch Rexroth Indramat belongs to the EFC Frequency Converters series and the internal model series EFC 5610. Designed for variable-speed control of induction and synchronous motors, the unit modulates the AC supply to match commanded torque and speed in automated machinery and process lines. As a member of the Frequency Converter product group and product line 02, it provides vector-based control for control cabinets where space is limited and open-chassis IP20 protection is acceptable.

For power connectivity, the converter accepts a three-phase supply in the range of 400 V (AC 380…480 V -15% / +10%). Under a heavy-duty rating, it delivers 30.0 kW of motor power with a continuous output current of 60.8 A, which corresponds to an apparent output of 40.0 kVA. The housing is rated IP 20, so it is intended for dry, dust-controlled enclosures. The frame is classified as size H, allowing panel mounting without external heat sinks. Internal standard vector control SVC maintains motor flux even at low frequencies, while the Flex-Control section with standard I/O supplies local digital and analog terminals for start, speed reference, and fault signaling.

Bus communication is provided through Modbus, enabling parameter access from PLCs without proprietary adapters. For functional safety, the integrated Safe Torque Off (STO) circuit disconnects gate drives so the motor cannot unintentionally energize. Electromagnetic compliance in industrial networks is supported by the industrial area, class C3 filter on the line side of the device. The standard control configuration requires no additional option cards, and the LCD display with potentiometer supports local adjustment of frequency, acceleration time, and diagnostic codes. Because the product is part of line 02 of the family, its parameter structure remains consistent with earlier EFC 5610 units.
