Product Description:

The EFC5610-5K50-3P4-MDA-7P-C10NN-NNNN is a frequency converter built by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. It converts fixed 50/60 Hz mains power into variable-frequency output so AC motors can be accelerated, decelerated, or held at precise speeds during automated production cycles. As a cabinet-mounted drive component, it links the plant supply to induction motors and simplifies speed regulation without mechanical gear changes in conveyors, pumps, and similar machinery.

The converter accepts 400 V (AC 380…480 V -15% / +10%) three-phase input, and this range matches common industrial feeders while providing sufficient DC-link voltage for motor flux. In heavy-duty operation, it is rated for 5.5 kW, allowing direct connection to mid-size pumps, fans, or conveyors that run on three-phase power, which helps balance current between lines and reduce cable heating. Control is based on standard vector control (SVC), where real-time flux estimation supports accurate torque response without external feedback. The integral filter is rated Class C3 for industrial areas, which helps limit conducted electromagnetic noise on the supply. Modbus networking provides cyclic setpoint exchange, and the control section uses a standard configuration with Flex-Control and standard I/O for straightforward wiring of start, stop, and fault signals. Size E frame dimensions favor retrofit into 200 mm wide enclosures, and a front standard LCD display with potentiometer supports local setup and status viewing.

The housing is classified as IP20, so it requires installation inside a protected cabinet when dust or moisture are present. The unit is part of the EFC 5610 family and the general 02 product line. The safety function is None, so any SIL-rated stop must be provided externally. The IP20 enclosure helps protect against accidental contact with internal live parts, but it is not sealed against airborne contamination or water exposure.
