Product Description:

The EFC5610-37K0-3P4-MDA-7P-DRNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat and placed in the EFC Frequency Converters series on the EFC 5610 platform. It belongs to product line 02 and the three-phase power class. In operation, the unit acts as a speed-controlling interface between the mains supply and induction motors used in conveyors, pumps, and general machinery in automated plants. The converter adjusts motor output to match process demand more closely than fixed-speed starting methods.

This converter is designed for grids that supply 400 V (AC 380…480 V -15 %/+10 %), and its heavy-duty channel drives motors rated up to 37.0 kW. Electronics are packaged in frame size H, providing room for cooling paths while maintaining cabinet compatibility, and the housing carries a protection rating of IP 20, so installation inside an enclosure is required where airborne contaminants exist. This arrangement suits enclosed cabinet mounting where controlled airflow and protected wiring are already part of the machine layout. Torque and speed regulation rely on Standard Vector control SVC, which works with the standard control configuration and Flex-Control I/O to keep motor operation stable under changing loads and during low-speed operation.

For networked control, the drive operates on Modbus, allowing direct parameter access from common PLCs without external gateways. Local interaction is handled by a Standard LCD display with potentiometer, which supports jogging and quick setpoint changes, while an Industrial area, class C3 EMC filter limits conducted and radiated emissions. This combination allows routine adjustments at the drive while still supporting command exchange through the automation network. A dedicated safety input enables Safe Torque Off (STO), removing motor-side energy without additional contactors.
