Product Description:

The EFC5610-7K50-3P4-MDA-7P-NNNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. Serving as the power interface between a three-phase supply and an asynchronous motor, it modulates output frequency and voltage so that speed and torque can be matched to process demands in industrial automation cells, material-handling lines, and HVAC drives. It is intended for variable-speed applications that require controlled acceleration and stable motor operation under changing load conditions.

This model connects to an AC network rated at 400 V with three-phase power, and the internal standard vector control (SVC) algorithm keeps flux constant while load varies. A heavy-duty motor output of 7.5 kW is the maximum continuous mechanical power the unit can deliver without derating. Protective coordination is simplified because the recommended Class J fuse is rated at 40 A, and the integrated C3 EMC filter limits conducted emissions in industrial environments. The housing has an IP20 rating, so the converter must be mounted in a clean enclosure but does not require additional gasketing. Standard LCD feedback with an integral potentiometer supports local parameter entry, while Modbus networking links the Flex-Control I/O section to higher-level PLCs.

Control outputs include a pulse train that reaches 32.0 kHz, enabling high-resolution speed feedback to external counters or controllers. Cabinet space is conserved because the unit measures 130 mm wide and 233 mm deep, allowing dense side-by-side installation on DIN rails or panels; overall height is 243 mm. With a mass of 4.3 kg, the unit remains compact for panel mounting, and M6 hardware passes through 6.5 mm mounting holes for secure fastening. Safe Torque Off (STO) circuitry provides a functional safety path that removes drive power without cycling upstream contactors, and separate open-collector and relay outputs supply status signals to interlock chains or alarm stacks.
