Product Description:

The EFC5610-3K00-3P4-MDA-7P-FCPNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series and identified within product line 02 and the EFC 5610 model group. Installed between the mains supply and an AC motor, the unit varies output frequency to regulate motor speed for pumps, fans, and general-purpose machinery on factory floors. By adjusting motor speed to match process demand, it can support smoother starts, steadier operation, and better control of airflow or fluid movement in common industrial applications.

The converter accepts a mains window centered on 400 V (AC 380…480 V, −15 % / +10 %) and is wired to a three-phase supply, a topology that balances current and reduces conductor size. In heavy-duty mode it can drive motors up to 3.0 kW, providing enough headroom for constant-torque loads such as mixers or hoists. The internal EMC filter is rated for an industrial area, class C3 environment, so additional line chokes are usually unnecessary outside sensitive laboratory zones. Mechanical integration is simplified by the housing’s frame size D, which aligns mounting holes and cable clearances with other devices in the EFC platform. These values set the operating range for protective devices, contactors, and cabinet space.

Drive commands are exchanged through Modbus, while the embedded Flex-Control board offers standard I/O for start, stop, and speed-reference signals. Closed-loop regulation is performed by Standard Vector control SVC, allowing accurate torque response without encoder feedback. An integrated LCD panel with potentiometer supports local tuning, and the enclosure’s IP 20 rating suits indoor cabinets where a touch-safe design is required but full dust sealing is not. For risk reduction, a certified Safe Torque Off (STO) channel disconnects gate drives so the motor cannot generate shaft torque during maintenance or emergency stops.
