Product Description:

The EFC5610-1K50-3P4-MDA-7P-NNNNN-L1NN frequency converter is manufactured by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. Classified in product line 02 and the EFC 5610 model branch, the device serves as a configurable AC drive that converts fixed-frequency utility power into a controlled output for induction machines used throughout automated conveying, pumping, and ventilation systems. Its role is to supply adjustable voltage and frequency so that connected motors can match process demands while improving energy efficiency and reducing mechanical stress.

When wired to a 400 V (AC 380…480 V −15% / +10%) supply, the converter draws power across three phases and supports a heavy-duty motor rating of 1.5 kW. This rating applies to continuous operation in demanding loads where the standard control configuration works together with Flex-Control I/O to maintain torque accuracy. An internal EMC filter specified for Industrial area, class C3 attenuates conducted emissions so the unit can share panels with sensitive electronics. The integrated LCD display with potentiometer allows parameter entry without external tools, and Safe Torque Off (STO) disables the drive’s output stage during service work. Protection is complemented by an IP20 housing that suits enclosure mounting.

The drive’s communication and mounting attributes support integration with modern automation cells. A built-in Modbus interface transfers setpoints and status bits to PLCs over a simple two-wire bus, eliminating the need for a separate gateway. Dynamic regulation is handled by Standard Vector control SVC, which calculates flux and slip in real time to hold speed during load transients. The hardware fits inside Frame Size C, allowing the use of common panel cutouts across the series. The control section follows the Flex-Control with Standard I/O layout, offering digital inputs, relay outputs, and an analog channel for process feedback.
