Product Description:

The EFC5610-75K0-3P4-MDA-NN-NNNNN-L1NN frequency converter is manufactured by Bosch Rexroth Indramat within the EFC Frequency Converters series. It is part of product line 02 and is installed between the mains and an induction motor. In automated conveying, pumping, and mixing systems, it regulates motor speed and torque to match process demand.

The unit accepts a nominal supply of 400 V and tolerates the full 380 to 480 V range. Power enters on a three-phase network, enabling balanced current without a neutral conductor. Under heavy-duty loading, the inverter can deliver 75.0 kW of mechanical power, making it suitable for high-capacity machinery. Torque production is managed by standard vector control (SVC), which adjusts output frequency to keep motor slip low. For supervisory control and diagnostics, a single-port interface supports Modbus communication, allowing start, stop, and parameter access from common PLCs. The drive uses the standard control configuration with a Flex-Control section and standard I/O, so digital and analog signals can be wired directly.

The housing carries an IP20 rating, so it must be mounted inside a cabinet while remaining protected from finger contact and moderate debris. An internal filter rated for industrial area, class C3 limits conducted emissions on long motor cables, which is important in plants with sensitive automation devices. Drive enable integrity is supported by Safe Torque Off (STO), which removes gate signals from the power stage to prevent unintended rotation. Mechanical dimensions match frame size J, which helps with cabinet layout. A molded dust cover replaces a local keypad, reflecting the display-free version used on this model. This enclosure style is intended for protected panel installation rather than direct exposure on the machine.
