Product Description:

The EFC5610-5K50-3P4-MDA-NN-NNNNN-NNNN is a frequency converter manufactured by Bosch Rexroth Indramat within the EFC Frequency Converters series. As an AC drive, it modulates power to run induction or synchronous motors at variable speed in conveyors, pumps, and other machinery. The unit belongs to the EFC 5610 model family and is supplied without an integrated display, so a dust cover can seal the front when local operator access is not required. This layout suits machines that are operated from a cabinet door interface or a higher-level controller rather than from the drive face.

The converter uses a three-phase configuration for incoming power. It is designed for a 400 V mains voltage and can operate from 380 V to 480 V within a tolerance of -15% to +10%, so it can connect to common industrial feeders without a transformer tap change. Internal regulation is handled by standard vector control (SVC), which maintains motor flux and supports stable torque at low speed. This control method helps maintain smooth acceleration and consistent response during changing load conditions. Parameter access and communications use Modbus, allowing simple integration with PLCs that poll serial registers. Under heavy-duty operation, the drive is rated for 5.5 kW of motor power.

The housing is built in frame size E, which helps keep cabinet layout consistent across the product line. The enclosure has an IP20 protection class, so the unit should be installed inside a closed panel away from conductive dust and dripping liquids. Conducted emissions are managed by a built-in C3 EMC filter for industrial areas, which helps limit interference on nearby control wiring. The control layer uses Flex-Control with standard I/O, providing terminals for start, stop, speed reference, and fault relay signals even when no fieldbus is used. Discrete terminal access also supports straightforward control wiring for standalone equipment and simple panel layouts.
