Product Description:

The EFC5610-18K5-3P4-MDA-7P-00002-L1NN is an AC drive unit produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. Installed between plant mains and an induction or synchronous motor, it modulates supply frequency and voltage to achieve commanded speed or torque profiles. This makes it suitable for conveyors, pumps, and general-purpose machinery that require adjustable motion in automated production lines. By varying output frequency and voltage together, the unit can respond to changing load conditions without requiring mechanical speed changes.

The converter accepts a mains input of 400 V (AC 380…480 V −15 % / +10 %), enabling installation on typical 400 V distribution systems without step-down transformers. In heavy-duty mode, it supports motor outputs up to 18.5 kW, which suits mid-power compressors and agitators. A three-phase topology balances line currents and helps reduce neutral return. Motion is regulated through standard vector control (SVC), which models motor flux to maintain torque at reduced frequencies. To support electromagnetic compatibility in industrial settings, an industrial-area class C3 filter is factory installed to limit conducted emissions.

Parameters can be set over Modbus or directly on the front panel by using the standard LCD display with a potentiometer. This arrangement supports both network-based setup and quick local adjustment during operation. The enclosure has an IP20 protection class, so the drive is intended for cabinet installation while guarding against accidental contact with energized parts. For functional safety, the integrated circuitry provides Safe Torque Off (STO), which removes motor torque during a stop request. The Flex-Control design with standard I/O and product line code 02 keeps control wiring consistent across the EFC 5610 platform.
