Product Description:

The FECG01.2-2K20-3P400-A-SP-MODB-01V01 frequency converter is produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. It is a 1st-generation V/f unit that adjusts the speed of standard three-phase induction motors in general automation. By converting the 400 VAC mains supply to a variable output frequency, the device lets conveyors, pumps, and fans run only as fast as the process demands. This control method suits applications that need reliable speed adjustment rather than closed-loop servo positioning. Its small mechanical size and integrated brake chopper simplify cabinet layout in both retrofit and new machinery.

Rated output power reaches 2.2 kW, and the converter can deliver a continuous current of 6 A when fed by a three-phase network within the 3 AC 380 to 480 V range. Short load peaks are accepted thanks to an overload margin of 200% for 1 second, and braking energy can be dissipated through an external resistor when needed. Frequency commands can be trimmed in steps as fine as 0.01 Hz, providing precise speed selection even at low shaft speeds. The unit uses V/f control and maintains rated performance up to a maximum ambient temperature of 40 °C. Input wiring passes through finger-safe terminals.

Motor breakaway is aided by a start-up capability of 150% at 5 Hz. The switching strategy, listed as SVPWM, improves voltage utilization and lowers acoustic noise. When a remote 0–10 V reference is used, output stability is held to an analog frequency tolerance of 0.05%, so speed drift stays low during continuous runs. The enclosure carries an IP20 rating, permitting installation inside protected cabinets without extra covers. Additional features include a built-in potentiometer for local jogging, ModBus RTU communication, and a 125 × 176 × 220 mm footprint that suits narrow control columns while leaving clearance for cooling airflow between -10 °C and +40 °C. Local jogging also supports short manual moves without an external speed reference.
