Product Description:

The EFC5610-18K5-3P4-MDA-7P-NNNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat and supplied within the EFC Frequency Converters series. It belongs to the EFC 5610 line and is part of product line 02. In automated plants, the unit modulates motor speed by adjusting output frequency, allowing precise process control and energy savings for three-phase induction motors used on conveyors, pumps, or fans. This operating role makes it suitable for applications that need controlled acceleration, stable running speed, and repeatable deceleration during routine machine cycles.

This converter is designed for a mains supply of 400 V (AC 380…480 V –15 % / +10 %) across three phases, matching common factory power grids. Motor output in heavy-duty service is rated at 18.5 kW, so the device can start and regulate mid-sized production drives without derating. Speed and torque are generated with standard vector control (SVC), and this control method maintains stable flux for better dynamic response than scalar V/Hz operation. Command and diagnostic data move over Modbus, which simplifies integration with existing PLC networks through a single twisted pair. The Flex-Control section with standard I/O accepts discrete signals for run, stop, or preset speed, while the LCD panel includes a potentiometer for local adjustments.

The enclosure meets IP20, permitting installation inside a ventilated cabinet where only solid objects larger than 12 mm can enter. A hardware-based Safe Torque Off (STO) circuit removes drive power to the motor when invoked, interrupting torque production at the output stage. Conducted emissions are limited by the built-in filter rated for industrial area class C3, which helps reduce interference on adjacent equipment. The mechanical envelope is identified as frame size G, which sets the mounting hole pattern and overall depth for panel installation.
