Product Description:

The EFC5610-3K00-3P4-MDA-NN-NNNNN-NNNN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. The unit modulates the output frequency supplied to asynchronous motors so that conveyor sections, pumps, and fan drives can be accelerated, decelerated, or held at a constant speed under closed-loop commands. By converting fixed-frequency mains power into a variable signal, it supports precise speed control without mechanical gear changes while keeping cabinet layouts compact. In variable-torque systems, this also helps the driven equipment operate at a speed that better matches the process demand.

The drive accepts a utility connection of 400 V (AC 380...480 V -15% / +10%) on three-phase power, permitting stable operation even with moderate supply fluctuations. Internally, its signal processing uses standard vector control SVC to maintain motor torque accuracy from low speed through rated frequency without external feedback devices. The control section uses Flex-Control with Standard I/O, providing discrete and analog terminals for run, direction, and process setpoint signals, so basic setup does not require add-on option cards. This arrangement supports common panel wiring and allows the drive to accept local commands from standard switches and reference signals. For networked installations, the converter communicates through Modbus, allowing parameter access and runtime monitoring from PLCs or supervisory software.

For heavy-duty applications, the unit can deliver 3.0 kW of shaft power when the connected motor is configured for the heavy-duty load curve. The housing corresponds to IP20, which protects internal electronics against finger contact and incidental solid intrusion when the converter is mounted inside a switchgear enclosure. A built-in EMC filter rated for industrial area, class C3 suppresses high-frequency emissions so that adjacent instrumentation is less affected on the plant floor. The housing uses Frame Size D, which helps the unit fit cabinet layouts intended for D-frame devices in the EFC 5610 line. Because the enclosure is intended for panel installation, it is typically used where a larger cabinet provides the surrounding physical protection and airflow path.
