Product Description:

The EFC3610-2K20-3P4-MDA-7P-NNNNN-NNNN frequency converter is manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. Within the EFC 3610 model series and product line 02, this drive converts constant utility power into a regulated output that allows three-phase induction motors to accelerate, decelerate, and hold a fixed speed under process control. Because the converter regulates motor frequency and voltage, it can match output speed to changing process demand instead of running the motor directly from the line. Its Flex-Control design with standard I/O supports local terminal operation or remote PLC commands. That arrangement lets the unit serve as a central speed regulator in conveyor sections, ventilation stages, and pumped circuit loops inside automated machinery.

The converter accepts a nominal input of 400 V (AC 380…480 V −15 % / +10 %) on three phases, matching common industrial mains networks. Inside, an Enhanced V/Hz control algorithm modulates the output frequency and voltage to sustain torque across the speed range, especially when the load reaches the heavy-duty rating of 2.2 kW. Protection against contact with live parts is provided by the IP 20 enclosure class, so the unit must be installed in a closed panel to limit dust exposure and direct touch. The control configuration is standard, and no integrated safety function is included, so emergency stop or safe torque off must be handled by upstream circuitry. This version follows the baseline feature set without factory-added options.

In operation, drive parameters can be adjusted with the Standard LCD display with potentiometer, while cyclic data exchange with higher-level controllers is available over Modbus through the built-in communication port. The front operator interface allows local setup without a separate external keypad. The incorporated EMC filter is rated for Industrial area, class C3, which helps limit conducted emissions when long motor cables are used. Mechanical layout corresponds to Frame Size D, which sets the mounting hole pattern and available surface area for heat dissipation. The housing also contains the Flex-Control section, the standard I/O terminals, and the EMC filter in one package.
