Product Description:

The EFC5610-2K20-1P2-MDA-NN-NNNNN-L1NN frequency converter is produced by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. As a member of the EFC 5610 model line, it acts as an adjustable-speed interface between a mains supply and an induction motor, allowing precise regulation of torque and speed in compact automation cells. The unit is part of product line 02 and is intended for applications that require vector control from a single-phase supply without external motion feedback devices.

Under heavy-duty rating, the drive delivers 2.2 kW to the connected motor, giving suitable capacity for pumps, fans, or conveyor axes. It accepts an AC input from 200 to 240 V AC, a range that matches regional low-voltage grids and tolerates a deviation of ±10%. The power stage is designed for single-phase feeders, so no phase-balancing transformer is required. Its mechanical proportions correspond to Frame size D, which helps maintain consistent cabinet spacing when multiple EFC units are installed. Protection reaches IP20, meaning fingers are shielded from live parts while airflow through the housing remains available for convection cooling.

Control tasks are handled through Modbus, allowing direct parameter access from PLCs without proprietary cards. Motor regulation relies on Standard Vector control SVC, which maintains flux-oriented operation and stable torque across a broad speed range. The internal logic uses Flex-Control with Standard I/O, so discrete signals and analog references can be wired directly to the terminal strip. Functional safety is provided by Safe Torque Off; when it is activated, the drive output transistors are inhibited without requiring a contactor. An EMC filter for industrial area class C3 is integrated, and a dust cover is fitted in place of a keypad.
