Product Description:

The FECG02.1-2K20-3P400-A-SP-MODB-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. It serves as the adjustable link between a three-phase plant supply and the motor by synthesizing variable-frequency, variable-voltage waveforms. In general-purpose automation, this function allows machine builders to match speed, positioning, and torque requirements without mechanical gear changes or contactors. This arrangement also lets the drive adapt motor speed to changing process demands while reducing abrupt electrical and mechanical transitions.

Its internal brake chopper paired with an external resistor dissipates regenerated energy during rapid stops. The converter carries a protection rating of IP20, so it is intended for mounting inside a ventilated cabinet. Output frequency can be trimmed in steps of 0.01 Hz, enabling fine speed tuning on synchronous or induction motors. High overload capability lets the drive deliver 200% for 1 second to overcome inertial peaks and sustain 150% for 60 seconds when the load remains elevated. A start-up torque of 150% at 5 Hz permits heavy loads to break away even before full base speed is reached. Magnetic-Flux PWM modulation, second-generation control electronics, and the built-in potentiometer further support smooth acceleration and deceleration profiles. These control functions help the motor respond predictably during acceleration, braking, and load changes.

The electrical ratings align with mid-power machinery, and continuous output power of 2.2 kW is available while the input network may vary across 3 AC 380 to 480 V on a three-phase feeder. Under rated conditions, the converter draws 8 A and supplies a continuous motor current of 6 A. Closed-loop operation covers a speed regulation span of 1:100, giving precise control from crawl to nominal motor speed. Total power throughput is 4 kVA, and the unit occupies a compact 220 × 125 × 176 mm envelope with a mass of 3.2 kg, matching the small-size front panel and mechanical size 1 classification. Modbus communication allows setpoint writing and diagnostic retrieval from a PLC without extra gateways, which supports direct integration into automated control systems.
