Product Description:

The EFC5610-18K5-3P4-MDA-7P-SVPNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat and supplied in the EFC Frequency Converters series. Within the EFC 5610 model range, it serves as an adjustable-speed drive that modulates the voltage and frequency delivered to three-phase induction or synchronous motors. By inserting variable-frequency control between the plant mains and the motor terminals, the unit supports precise speed regulation, soft starting, and process-specific torque adaptation for conveyors, pumps, and fan arrays. It belongs to product line 02 in the Frequency Converter product group.

The converter is designed for Three phases, ensuring balanced current draw from industrial feeders. It accepts a nominal input of 400 V (AC 380…480 V -15 % / +10 %), so it can connect directly to common 400 V distribution networks without an additional transformer. In heavy-duty service, the power section is rated for 18.5 kW, enabling full-load operation of mid-sized production motors. Speed and torque are controlled through Standard Vector control SVC, which helps maintain motor torque at low frequencies. The control section uses the standard configuration with Flex-Control design and standard I/O, while application data and parameter edits are shown on a standard LCD display with a potentiometer. For drive coordination or PLC supervision, the unit communicates over Modbus, a widely used serial protocol for multidrop cabling on the factory floor.

An internal EMC filter rated for Industrial area, class C3 attenuates conducted emissions so the drive can be installed alongside sensitive instrumentation. The housing carries an IP 20 rating, which helps protect against accidental contact with live parts when the converter is mounted in a switchgear cabinet. Functional safety is provided through Safe Torque Off (STO); when this circuit is triggered, the power stage is reliably de-energized without mechanical relays. Mechanical dimensions correspond to frame size G, allowing panel layouts to match mounting holes and airflow clearances across the EFC series.
