Product Description:

The EFC5610-55K0-3P4-MDA-NN-NNNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat and supplied within the EFC Frequency Converters series. As a variable-speed power stage, the unit modulates AC input to provide regulated output for induction or permanent-magnet motors used in material handling, pumping, and general factory automation. It is intended for applications that need adjustable motor speed and controlled acceleration during routine machine operation.

This converter operates from a nominal mains supply of 400 V and tolerates 380 to 480 V within a -15% to +10% input window, so it can be connected directly to standard industrial power networks without an additional transformer. In heavy-duty operation, it supports motors up to 55 kW, enabling startup and sustained torque for large fans, compressors, or conveyors. Closed-loop current regulation is handled by standard vector control (SVC), which helps maintain stable shaft speed under fluctuating mechanical load. The power section is designed for three-phase power, so single-phase sources are not compatible. An integrated EMC filter rated for industrial area class C3 limits conducted emissions, and the housing has an IP20 protection rating, which means live parts are finger-safe but the drive must be installed inside a control cabinet for dust and water protection.

The safety input supports Safe Torque Off (STO), allowing the drive to remove motor power without opening the main contactor during emergency stops. Parameter access and fieldbus bridging can be handled through the integrated Modbus interface, which supports setup with many PLC platforms. The unit includes Flex-Control with standard I/O for discrete logic signals, and the mechanical layout corresponds to frame size I. A dust cover replaces a keypad on the front panel when local operator control is unnecessary, which suits installations that rely only on remote commands.
