Product Description:

The EFC5610-110K-3P4-MDA-7P-NNNNN-L1NN frequency converter is built by Bosch Rexroth Indramat for the EFC Frequency Converters series. It sits between a three-phase mains supply and an AC motor, varying output frequency to control speed in conveyors, mixers, packaging lines, and other industrial equipment. The unit belongs to the EFC 5610 model range and is intended for cabinet installation, where it supports adjustable motor operation in compact drive systems.

The converter accepts a 400 V AC (380 to 480 V, -15% / +10%) input, and the power stage is arranged for three-phase power so it can connect directly to standard industrial mains. Motor regulation is handled by standard SVC vector control, which supports stable speed response and useful torque performance across a broad operating range. A factory-installed EMC filter rated for an industrial-area Class C3 environment helps reduce conducted emissions on plant power networks. Mechanical installation is supported by frame size K, while the Flex-Control section with standard I/O provides configurable terminals for start, stop, and speed reference functions. A standard LCD display with a potentiometer allows local setup, and the unit is assigned to Line 02.

For higher-demand duty, the converter provides a heavy-duty output rating of 110.0 kW, making it suitable for large pumps, fans, and extruders that need controlled acceleration and speed adjustment. Network communication is available through Modbus, allowing a PLC to exchange status words and frequency setpoints without an additional gateway. Personnel protection is supported by the built-in Safe Torque Off (STO) circuit, which removes torque-producing power from the motor while keeping the control electronics active. The enclosure has an IP20 rating, so it helps limit accidental contact with internal parts while still allowing the airflow needed for cabinet ventilation.
