Product Description:

The EFC5610-55K0-3P4-MDA-7P-SVPNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat within the EFC Frequency Converters series and product line 02. Installed in a control cabinet, the drive modulates the voltage and frequency sent to an asynchronous motor rather than supplying fixed mains power directly to the motor. By adjusting these values, it lets conveyors, pumps, and fans match speed to process demand while limiting electrical peaks and keeping torque stable under variable load.

This converter is intended for heavy-duty motors up to 55.0 kW. Its power section accepts a nominal line supply of 400 V, and the design tolerates fluctuations between 380 and 480 V. Because the unit is wired for three phases, it can connect directly to typical plant distribution networks without phase conversion. An integrated EMC filter rated for Industrial area, class C3 limits conducted interference so the drive can operate alongside other equipment in the same cabinet. The enclosure has an IP 20 protection class, which helps prevent accidental contact with live parts inside control cabinets. Frame size I keeps mounting dimensions consistent, and the Flex-Control section with standard I/O supplies basic digital and analog terminals for local commands and signal exchange.

The control layer exchanges data with higher-level PLCs over Modbus, allowing setpoint writing and status polling through a single twisted-pair link. Torque production is governed by Standard Vector control SVC, so the converter can keep motor speed steady when load changes. For personnel and machine safety, the hardware contains Safe Torque Off (STO), which removes drive energy without mechanical contactors. Parameter editing and local jogging are handled on a Standard LCD display with potentiometer, which gives direct access to operating values and speed adjustment.
