Product Description:
The EFC3610-1K50-3P4-MDA-7P-NNNN-NNNN frequency converter is built by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. As a standalone AC drive, it turns fixed-frequency mains power into a variable output suited for regulating induction motor speed in pumps, fans, and material-handling equipment. By varying the motor’s electrical frequency, the device enables energy-saving process control, soft starting, and accurate torque adjustment without the need for mechanical throttling or gear changes in industrial automation. The converter is intended for cabinet installation inside control panels where space-constrained drives are required.
Incoming power is accepted at 400 V (AC 380...480 V -15% / +10%), a range that lets the drive operate on common industrial supply systems without additional transformers. Once energized, the converter modulates output with Enhanced V/Hz control, a scheme that keeps the volts-to-hertz ratio constant so motor flux stays stable under changing speed commands. Network integration is available through Modbus, allowing parameter access from PLCs and HMIs. The integrated EMC filter has an Industrial area, class C3 rating, which limits conducted emissions on long motor cables. The housing meets IP 20, indicating finger-safe protection when mounted inside an enclosure.
The power stage uses three-phase power, matching standard industrial mains grids and helping maintain balanced current draw. Within frame size C, the converter delivers a heavy-duty output of 1.5 kW, giving adequate margin for centrifugal loads started at low frequencies. I/O handling follows Flex-Control with Standard I/O, so terminals can be reassigned for run, direction, or speed reference signals while the overall control configuration remains standard. Operators view parameters on a standard LCD display that includes an integral potentiometer for local setpoint trimming. The model carries the EFC 3610 designation in product line 02.
