Product Description:

The EFC5610-37K0-3P4-MDA-7P-FCPNN-L1NN is a frequency converter built by Bosch Rexroth Indramat for the EFC Frequency Converters series. The unit converts fixed-frequency mains power into a variable output that lets induction motors change speed for pumps, fans, and material-handling drives. By integrating drive electronics, a user display, and I/O in one enclosure, it simplifies installation inside control cabinets and supports closed-loop automation where precise speed and torque regulation are required.

This model communicates with higher-level controllers through Modbus, allowing parameter access over a two-wire serial link. Motor flux is regulated by standard vector control (SVC); this algorithm maintains dynamic torque even at low speeds, which is useful in lifting or tensioning duties. For electromagnetic compatibility, it contains an internal filter rated for Industrial area, class C3, so additional external suppression is not usually needed in plant environments. The converter accepts a three-phase supply centered on 400 V, with an operating range of 380 to 480 V and a tolerance of -15% to +10%, matching common factory distribution networks. In heavy-duty mode, it can deliver 37.0 kW to the motor without derating. Power is routed through three output terminals because the drive is designed for three-phase motor current.

Protection against accidental restart is provided by the integrated Safe Torque Off (STO) function, which removes gate signals to the power stage without cutting mains power. The housing meets IP20, offering finger-safe access for panel-mounted operation while relying on the cabinet for dust and moisture protection. Cooling airflow and terminal spacing are sized for the physical H frame, so the same mounting pattern can be maintained across drives of similar rating. An LCD panel with potentiometer remains available for local adjustment, and Flex-Control standard I/O supports direct wiring of sensors or run commands without extra interface modules.
