Product Description:

The EFC5610-2K20-3P4-MDA-7P-C10NN-NNNN is a frequency converter built by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. It conditions incoming AC power and produces a variable output frequency for speed control in industrial drives such as conveyors, pumps, and process equipment. By modulating voltage and frequency together, the unit keeps motor current within intended limits while delivering the torque needed by heavy-duty loads.

It accepts a mains supply of 400 V (AC 380–480 V -15 % / +10 %) on a three-phase network, matching standard plant power systems. In heavy-duty mode, the inverter supports motors rated at 2.2 kW and maintains stable flux through its Standard Vector control SVC mode. A Flex-Control section with standard I/O provides eight digital inputs, two relay outputs, and analog channels for speed reference or feedback. The internal layout uses frame size D, which keeps the cooling components, DC link, and terminals in a consistent cabinet footprint while leaving space for line reactors and braking resistors.

Integration into supervisory systems is handled through Modbus, which exchanges process data at configurable baud rates without optional communication boards. Operators adjust parameters directly with the standard LCD display with potentiometer, which allows local setup, speed adjustment, and fault acknowledgment from the front of the unit. The built-in industrial area, class C3 EMC filter reduces conducted noise on the supply lines when the converter is installed near sensitive sensors and PLC I/O. The housing is rated IP 20, which helps prevent accidental contact with live parts, but the unit still requires installation in an enclosure for broader protection. Because no dedicated safety function is included, external circuits must interrupt the drive enable line when an emergency stop or safe torque off function is required.
