Product Description:

The EFC5610-4K00-3P4-MDA-7P-FCPNN-NNNN is a frequency converter produced by Bosch Rexroth Indramat for the EFC Frequency Converters series. Classified under product line 02, it is intended for speed regulation of three-phase induction motors in conveyors, pumps, and general machinery. By transforming constant mains frequency into a variable output, it matches motor speed to real-time load and lowers energy consumption. A Flex-Control section with standard I/O, combined with a standard control configuration, simplifies wiring to PLCs and discrete automation signals.

The converter accepts supply power at 400 V (AC 380...480 V -15% / +10%), allowing operation on most industrial networks even when voltage drifts from nominal values. It is designed for three-phase power, which balances line currents and minimizes torque ripple. In heavy-duty mode, the drive can regulate motors up to 4.0 kW, making it suitable for medium process equipment without auxiliary soft-start devices. The internal algorithm relies on standard vector control (SVC), which helps maintain precise torque at low frequencies. The housing has an IP20 protection class, giving finger-safe access for cabinet installations while still requiring placement inside a dust-protected enclosure.

Fieldbus connectivity is provided through Modbus, enabling parameter adjustment and status polling over a simple two-wire link that is widely supported by PLCs and HMI panels. Conducted emissions are reduced by an integrated filter rated for industrial area, class C3, which helps limit the need for additional external EMC hardware. The unit uses frame size D, which keeps mounting dimensions and airflow paths consistent across the EFC 5610 range. For local setup, the front panel includes a standard LCD display with a potentiometer, so menus can be viewed and the speed reference can be adjusted directly. The unit omits a dedicated safety function, relying on upstream contactors or safety relays where required.
