Product Description:

The EFC5610-3K00-3P4-MDA-7P-FCPNN-NNNN frequency converter is manufactured by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. It controls variable-speed three-phase induction motors by converting fixed line power into adjustable voltage and frequency, allowing precise control of pumps, fans, and conveyors. The unit uses a Flex-Control platform with standard I/O so that run commands, speed references, and fault signals can interface directly with PLC terminals. By regulating motor speed instead of relying on mechanical throttling, it reduces energy demand and softens acceleration to help protect driven equipment.

The electrical section is designed for a supply of 400 V (AC 380…480 V -15 % / +10 %), allowing direct connection to typical factory mains. It operates on a three-phase input, which distributes current symmetrically and limits neutral currents. In heavy-duty mode, the drive delivers 3.0 kW of output power, which suits mid-range centrifugal and positive-displacement loads. Torque production is handled by standard vector control SVC, a sensorless algorithm that maintains flux at low speed for steady breakaway force. For supervisory control, the inverter communicates through Modbus, so start, stop, and frequency references can be issued over a two-wire RS-485 link. The standard control configuration keeps digital inputs preassigned yet still editable, so basic control logic can be adapted without extra option cards.

Electromagnetic compliance is supported by the built-in industrial-area Class C3 filter, which lowers conducted noise on both supply and motor leads. Status data is viewed on the standard LCD display with a potentiometer; the keypad shows output frequency while the dial allows quick manual adjustment during test runs. Mechanical dimensions follow frame size D, giving a consistent mounting footprint and heat-sink depth across this power class. The enclosure carries an IP 20 rating, which provides finger protection but requires installation in a protected control cabinet. The converter does not include integrated safety functions, so external contactors or relays are required where STO or SS1 functions are needed.
