Product Description:

The EFC5610-4K00-3P4-MDB-NN-FCPNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat and assigned to the EFC Frequency Converters series. As a drive component, it modulates fixed-frequency mains power so three-phase induction motors can run at variable speed or torque in automated lines, pump stations, and material-handling cells. The design follows the EFC 5610 platform and places it in product line 02 for installations that do not require an integrated operator panel. This arrangement suits panel-mounted systems where local keypad access is not the primary operating method.

This converter accepts a mains window centered on 400 V (AC 380…480 V –15% / +10%) and is wired to a three-phase supply. Under heavy-duty ratings, it supports motors up to 4.0 kW, and the drive uses standard vector control (SVC) for torque control. An internal RFI network is built to the Industrial area, class C3 filter level, reducing conducted interference on long cable runs. Control electronics follow the Flex-Control scheme with standard I/O, which permits direct wiring of limit switches and analog references while keeping the control configuration in a standard profile. The cold-plate layout has IP20 protection, and its dimensions simplify panel planning for mid-range power sections.

Fieldbus data exchange is handled through Modbus, allowing parameter access from PLCs without additional interface cards. The converter uses frame Size D, which helps determine cabinet spacing and mounting clearances. Functional safety is provided by the hardware-wired Safe Torque Off (STO) input, which disables gate drive energy so motor torque drops to zero without cutting mains power. Thermal energy is dissipated through a baseplate with an IP 20 Cold Plate design, supporting external heat-sink attachment in sealed cabinets. A dust cover replaces the front keypad, so operation is intended through a remote HMI or software tools rather than through a built-in local display.
