Product Description:

The EFC5610-7K50-3P4-MDA-7P-NNNNN-NNNN belongs to the EFC Frequency Converters series from Bosch Rexroth Indramat. As a variable-speed AC drive, it converts fixed-frequency mains power into a regulated output so users can match motor speed to process demands, reduce energy use, and limit torque shocks on connected equipment. Installed between the supply network and an induction motor, it supports open-loop vector control for pumps, fans, and material-handling machines. This arrangement gives the drive direct control over output frequency and voltage while helping the motor respond smoothly to changing process conditions.

For heavy-duty loading, the converter supports a motor rating of 7.5 kW, which states the maximum motor power it can regulate without derating. Incoming supply must remain within 400 V AC (380 to 480 V, -15/+10%), and the internal DC bus and output stage are matched to that operating window. Speed regulation is handled by standard vector control (SVC), which separately manages flux and torque so low-speed operation stays stable. An integrated EMC filter qualified for industrial area class C3 helps reduce conducted emissions on long motor leads. The enclosure has an IP20 rating, so the converter is intended for installation inside a control cabinet where protection against direct finger contact is required.

System integration is supported by the built-in Modbus interface, which allows a controller to read status words and adjust setpoints over a two-wire network instead of relying only on discrete I/O. The mechanical layout uses frame size E, which sets the heat-sink footprint and cabinet depth used for this drive size. The power section is designed for three-phase operation, which balances input current and removes the need for a neutral conductor. Local setup is done through a standard LCD display with potentiometer, allowing motor jogging, acceleration-ramp adjustment, and alarm review without connecting a PC. The Flex-Control section includes standard I/O, so switches, sensors, and contactors can be wired directly without extra option cards.
