Product Description:

The EFC5610-3K00-3P4-MDA-7P-00002-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. The unit interfaces between a factory’s three-phase mains and an AC motor, adjusting output frequency and voltage so that conveyor belts, pumps, or fans run at commanded speeds. By modulating the motor’s electrical supply, the converter supports precise process control, reduced inrush current, and optimized energy use in continuous or cyclic industrial automation tasks. It is suited to variable-speed applications that require smooth acceleration and stable motor response as load conditions change.

Incoming power is nominally rated at 400 V AC, with a tolerance range of 380 to 480 V, allowing the device to operate on common factory feeds without an autotransformer. It is wired for three-phase power, which balances line currents and supports higher motor torque than single-phase supplies. Under heavy-duty loading, the drive delivers 3.0 kW of mechanical power to the motor. Drive regulation is performed by standard vector control (SVC), which provides slip compensation and stable torque at low speeds. For supervisory integration, the converter uses Modbus, allowing PLCs to read status words or write operating setpoints over a simple serial link. Control configuration is fixed as Standard, and the Flex-Control section provides digital and analog I/O for local commands.

The electronics sit in an IP 20 housing, so the unit must be mounted inside an enclosure and can rely on convection airflow for cooling. Machine safety is addressed through the integrated Safe Torque Off (STO) circuit, which disconnects gate drive to the power stage without relying on contactors. Mechanical layout follows Frame Size D, which keeps mounting and cable clearances consistent for this housing format. An internal electromagnetic filter certified for industrial areas to class C3 reduces conducted noise returning to the mains. Operators interact through a standard LCD display with potentiometer, and the product is identified as line 02 within the Bosch Rexroth converter portfolio.
