Product Description:

The EFC5610-37K0-3P4-MDA-7P-NNNNN-L1NN is a frequency converter built by Bosch Rexroth Indramat for the EFC Frequency Converters series. It modulates the voltage and frequency supplied to three-phase induction motors so production lines, pumps, or material-handling systems can vary speed under closed-loop control without mechanical gear changes. The unit sits in product line 02 and uses a standard control configuration, providing a consistent platform for drive tasks that require scalable vector control and integrated safety. This arrangement supports variable-speed motor operation while helping connected equipment respond smoothly to changing process demands.

This model connects to a three-phase mains supply rated at 400 V (AC 380…480 V -15% / +10%) and delivers a heavy-duty motor output of 37.0 kW. Command and diagnostic data travel over Modbus, allowing the converter to exchange setpoints and status with PLCs through a straightforward serial link. Torque production is regulated by Standard Vector control SVC; the algorithm monitors current and voltage to maintain constant flux during load swings. For electromagnetic compatibility inside industrial switchgear, the integrated filter is specified as Industrial area, class C3. This combination supports stable speed regulation and dependable response during normal load changes.

The control electronics follow the Flex-Control with Standard I/O design, so digital and analog terminals are already present for hard-wired sensors, contactors, and thermal switches. All components are arranged in frame size H, giving the unit a clear cabinet footprint and terminal layout. A protection rating of IP 20 allows mounting inside ventilated enclosures where touch-safe parts are required but liquid exposure is limited. Functional safety is addressed with Safe Torque Off (STO), which removes torque-producing output when the safety channel is activated. This feature supports machine safety functions without requiring separate external contactors for every stop command.
