Product Description:

The EFC5610-7K50-3P4-MDB-7P-NNNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. The unit belongs to product line 02 and is intended for compact cabinet mounting. It takes incoming plant voltage and produces a regulated, variable-frequency output that lets industrial controllers adjust motor speed as process demands change, improving cycle accuracy and lowering energy use in pumps, fans, and material-handling equipment.

Communication with supervisory systems occurs over Modbus, allowing straightforward parameter read and write operations from a PLC or SCADA workstation. The power section accepts 400 V AC supplies that can range from 380 V to 480 V within a -15% to +10% tolerance, so it can be wired directly to typical European or North American 460 V distribution panels. In heavy-duty operation, the converter supports motors up to 7.5 kW, providing constant torque for mixers or extruders without derating. An integrated EMC filter qualified for industrial area class C3 suppresses radio-frequency noise conducted back onto the mains. Thermal energy is removed through a baseplate interface, and the enclosure carries an IP 20 Cold Plate rating, so the unit must be installed inside a closed control cabinet.

The drive’s control stage uses Standard Vector control SVC to maintain constant torque even at low speed. Flex-Control with standard I/O provides terminals for enable, analog speed reference, and fault relay, and the control configuration is standard, so no plug-in options are required. Operation is handled through a Standard LCD display with potentiometer, eliminating the need for an external keypad. Mechanically, it uses frame size E, which keeps mounting consistent across the family. For machine safety, Safe Torque Off (STO) disables gate signals to the IGBTs, removing torque without opening the mains breaker. The unit is intended for three-phase networks.
