Product Description:

The EFC5610-18K5-3P4-MDA-NN-NNNNN-NNNN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. It provides variable-speed regulation for three-phase motors in automated plants, matching motor torque to process demands and reducing mechanical stress on connected equipment. The unit is supplied under product line 02 with a standard control configuration, and a dust-covered front replaces an integrated display. It is intended for cabinet mounting rather than open installation on the machine.

This converter is designed for a rated network of 400 V (AC 380...480 V -15% / +10%) across three incoming lines and can deliver up to 18.5 kW of heavy-duty motor power. Output modulation is handled by Standard Vector control SVC, which helps maintain motor flux and torque accuracy under varying loads. The integrated EMC filter is classified for Industrial area, class C3, so additional external suppression is usually unnecessary in industrial switchboards. The power section is housed in frame size G, and the input uses three-phase power to support balanced current draw and help minimize neutral-line disturbances.

The control section uses Modbus connectivity, giving the drive direct parameter access from PLCs or HMIs through a two-wire RS-485 link. Its control platform is Flex-Control with Standard I/O, which supplies discrete inputs and relay outputs for speed commands, run-permissive states, and fault signaling without expansion cards. The enclosure has a protection class of IP 20, which limits contact with live conductors while allowing cabinet airflow around the unit. Because the drive does not include an internal display, setup is handled through the communication port or by temporarily removing the cover to attach an external keypad. Parameters can be stored in EEPROM before the cover is reinstalled.
