Product Description:

The EFC3610-0K40-3P4-MDA-NN-NNNNN-NNNN is a frequency converter manufactured by Bosch Rexroth Indramat within the EFC Frequency Converters series. In an automation cell, it sits between the mains supply and an induction motor, changing the supply frequency so motor speed and torque can match process needs instead of remaining fixed at line frequency. This operating method supports energy-efficient pump, fan, and conveyor duties while remaining suitable for plant three-phase 400 V power systems.

The drive accepts a nominal input of 400 V AC (380-480 V -15% / +10%) on a three-phase supply. It delivers up to 0.4 kW of motor power in heavy-duty mode, which makes it suitable for small mechanical loads. Speed regulation is handled by Enhanced V/Hz control, a scalar method that maintains the intended volts-per-hertz ratio so motor flux stays stable during acceleration and deceleration. System integration is supported by a built-in Modbus interface, allowing basic parameter access from PLCs or HMIs without extra gateways. The converter uses a standard control configuration and belongs to product line 02 within the EFC 3610 range.

Physical construction follows Frame Size B, which matches the mounting hole pattern and enclosure depth used for this housing size in panel layouts. The control section uses Flex-Control with Standard I/O, so the unit provides six digital inputs, one analog input, and one relay output for hardwired start, stop, and speed reference signals when fieldbus control is not used. An internal EMC filter rated for industrial area, class C3 reduces conducted emissions on long motor leads, and the housing meets IP 20, which provides finger-safe protection when installed inside a control cabinet. The front panel is closed by a dust cover because the unit is supplied without a display.
