Product Description:

Bosch Rexroth Indramat manufactures the EFC3610-0K40-3P4-MDA-NN-00001-NNNN frequency converter in the EFC Frequency Converters series. The unit is an AC drive that converts fixed mains power to variable voltage and frequency so induction motors can match process demands in automated material-handling, pumping, and ventilation systems. Its Flex-Control platform with standard I/O supports decentralized panel layouts and maintains straightforward wiring to sensors and actuators on the machine. It is well suited for applications that need basic ramp control and consistent motor response without complex feedback hardware.

The power section is optimized for a rated supply of 400 V AC (380 to 480 V, -15% / +10%). It regulates motor speed using Enhanced V/Hz control, a scalar method that maintains a proportional ratio between voltage and frequency across the operating range. Communication over Modbus allows basic parameter access from a PLC or HMI without option cards. For electromagnetic compatibility, the integrated filter is classified for industrial area, class C3, which suits higher-power installations with long motor leads. The enclosure is rated IP 20, so the drive is intended for cabinet mounting where contact with live parts is restricted.

Within this rating envelope, the converter delivers 0.4 kW of heavy-duty motor output, which suits small fan wheels or light conveyor zones that still need accurate speed adjustment. The input terminals accept a three-phase supply, so balanced line currents are expected and harmonic loading is reduced compared with single-phase variants. Mechanical integration is simplified by the compact Frame Size B, which shares drilling patterns with other 3610 models. The front plate has no display and a dust cover, so settings are accessed through external software or a remote keypad. The dust cover also helps keep debris away from the front-panel opening during normal cabinet use.
