Product Description:

The EFC5610-22K0-3P4-MDA-7P-00002-L1NN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. As a variable-speed drive, it modulates the power supplied to an AC motor so automation equipment can match torque and speed to process demands instead of operating only at fixed line frequency. This unit belongs to product line 02 and is intended for cabinet installation in factory environments where compact motor control and integrated diagnostic feedback are required.

Its input network accepts 400 V (AC 380…480 V −15 % / +10 %), so common three-phase utility feeds can be connected without an external transformer. The heavy-duty rating is 22.0 kW, which is the maximum mechanical output the converter can deliver to a matched motor during continuous high-torque duty. The drive uses a three-phase supply and motor output to maintain balanced current sharing and help reduce conductor size. Speed and torque are regulated by Standard Vector control SVC, which compensates for slip and load changes without requiring an encoder. Electromagnetic interference is limited by the integrated filter rated for Industrial area, class C3, making the unit suitable for heavy industrial installations. Control functions are handled by the Flex-Control section with standard I/O, and the front panel uses an LCD display with a potentiometer for local adjustment.

The housing is built in Frame Size G, which matches the enclosure format used for this model range. The enclosure has an IP 20 rating, providing finger-safe protection when the unit is installed in a closed electrical cabinet with forced airflow. Functional safety is provided by Safe Torque Off (STO), which removes motor torque by disabling the drive output without using a mechanical contactor. Networked control and parameter transfer are available through Modbus, allowing straightforward communication with compatible PLC and automation systems.
