Product Description:

Bosch Rexroth Indramat manufactures the EFC5610-0K40-3P4-MDA-NN-NNNNN-L1NN as part of the EFC Frequency Converters series. This drive converts fixed mains power into a variable output waveform, allowing precise speed regulation of asynchronous motors used in automated conveying, dosing, and ventilation systems. By altering frequency and voltage, it supports smoother acceleration and deceleration, minimizes mechanical shock, and helps machinery meet cycle-time demands while limiting energy consumption in continuous-duty industrial environments.

For electrical integration, the converter accepts a supply of 400 V (AC 380…480 V -15 % / +10 %) on a three-phase network, enabling symmetrical loading of plant switchgear. Motor output in heavy-duty mode is rated at 0.4 kW, which suits small fans, pumps, and feeders. Drive dynamics are handled by standard vector control SVC, which maintains torque at low speeds without encoder feedback. Parameter access is available through Modbus, allowing the unit to exchange data with PLCs or SCADA terminals. The internal Flex-Control section with standard I/O provides digital and analog terminals for run commands, speed references, and fault signals, while the front face uses a dust cover instead of a display to reduce ingress points in particulate atmospheres.

The housing has an IP 20 protection class, so live parts are shielded from fingers, but the unit must be installed inside a control cabinet. When an emergency stop is required, the integrated Safe Torque Off (STO) circuit interrupts gate signals to the power stage and prevents unintended motor motion. To limit conducted emissions on the mains side, an industrial area, class C3 EMC filter is built in. The drive uses frame size B, which fits installations designed for this mounting format and enclosure size.
