Product Description:

The FECG02.1-0K75-3P400-A-SP-MODB-01V01 frequency converter is manufactured by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. It serves general automation installations by translating fixed utility frequency into a variable output so asynchronous motors can run at commanded speeds. The device is part of the second-generation platform, uses V/f regulation with SVPWM switching, and links to higher-level controllers through a ModBus interface. An internal brake chopper works with an external braking resistor to absorb regenerated energy during quick deceleration.

The converter accepts a three-phase input within 3 AC 380 to 480 V and produces up to 2.5 A of continuous output current, matching the thermal limits of its small panel enclosure. At rated load, it supplies 0.75 kW to the motor, a value appropriate for light conveyors, mixers, or indexing tables. Speed commands can be trimmed in steps of 0.01 Hz, allowing fine adjustment when the application demands tight flow or positioning tolerance. High breakaway capability is provided by a start-up torque of 150% at 5 Hz, letting the motor overcome static friction before transitioning to normal running conditions. The size 1 housing measures 125 mm wide, 176 mm deep, and 220 mm high while weighing only 3 kg, which simplifies cabinet layout in space-constrained equipment.

The overload profile permits 200% for 1 second and 150% for 60 seconds, supporting momentary surges such as product jams without tripping the drive. A speed control ratio of 1:100 extends the usable motor range down to low frequencies, and this is complemented by the built-in potentiometer for local adjustments. The enclosure has a rating of IP20, and operation is permitted up to 1000 m altitude with humidity below 90%. The converter is design version 1, and the SVPWM carrier helps manage switching losses during operation.
