Product Description:

The EFC5610-0K40-3P4-MDA-7P-NNNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. The unit belongs to the EFC 5610 product family and is intended for variable-speed control of induction motors in automated machinery, conveyors, and pump sets. By adjusting output frequency and voltage, it allows the connected motor to match changing process demand while reducing unnecessary energy use. This makes it suitable for applications that need controlled acceleration, steady running speed, and repeatable motor response during normal machine operation.

Communication with upper-level PLCs is provided through Modbus, enabling parameter access and start-stop commands over a two-wire serial link. The inverter accepts a line supply of 400 V (AC 380–480 V -15%/+10%), so it can be installed on standard industrial distribution networks without a transformer. Motor regulation is performed with standard vector control (SVC), which calculates flux and torque in real time to help maintain speed accuracy as load changes. Under heavy-duty loading, the converter is rated for 0.4 kW of motor power, which suits small induction-motor applications. The plastic housing carries an IP 20 protection class, so it provides finger-safe access protection and is intended for installation inside a control cabinet.

An integrated EMC filter qualified for industrial area, Class C3 limits conducted emissions, so extra line chokes are not required in most plant installations. When an emergency stop is triggered, the built-in Safe Torque Off (STO) channel disables gate signals to the power stage, eliminating unintended motor torque without external relays. The mechanical layout uses frame size B, which helps maintain consistent mounting across this product family. The power section is designed for three-phase input, helping distribute line current across the supply conductors during operation.
