Product Description:

The EFC5610-11K0-3P4-MDA-7P-DRNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat in the EFC Frequency Converters series. It modulates a fixed-frequency supply into a variable-frequency output for induction motors, enabling accurate speed and torque control in pumps, fans, and conveyor drives used throughout automated production lines. This allows connected machines to match motor speed to process demand instead of running continuously at line frequency. Because output frequency and voltage are adjusted together, the drive can also reduce mechanical stress during startup and speed changes.

The unit supports a heavy-duty motor load of 11.0 kW. It connects directly to mains rated at 400 V (AC 380…480 V −15 % / +10 %), matching common industrial distribution levels. The power section uses three-phase power, which helps balance current across the supply and reduce harmonics. Speed regulation is handled by standard vector control (SVC), maintaining constant torque even at low output frequencies. Housing protection is limited to IP 20, so the converter should be installed inside an enclosure where dust or spray may be present.

System integration is supported through the built-in Modbus interface, allowing parameter access and diagnostics from a PLC without extra hardware. The converter includes an EMC filter rated for industrial area, Class C3, which helps limit conducted emissions in plant installations. A functional safety channel provides Safe Torque Off (STO), disconnecting torque-producing energy to the motor circuit without external contactors. Operators set references on a standard LCD display with potentiometer mounted on the front panel. Frame size F, the Flex-Control with Standard I/O board, and product line 02 support common panel layouts, while the control hardware provides eight digital inputs and two relay outputs for localized sequencing tasks.
