Product Description:

The FECG02.1-75K0-3P400-A-BN-MODB-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. As a second-generation unit for general automation, it converts fixed three-phase mains power into variable voltage and frequency for induction motors that need controlled speed changes during operation. The converter communicates over Modbus networks, uses V/f control with a PID regulator, and applies space-vector PWM to shape the output waveform. An external brake chopper can also be connected when braking energy must be managed during deceleration.

Electrical performance is led by a rated power of 75 kW and a continuous current capacity of 152 A, making the unit suitable for large motor loads in industrial systems. The input stage accepts 3 AC 380 to 480 V from the 400 VAC class and provides an adjustable output frequency up to 599 Hz for applications that require a wide speed range. Relay contacts switch 230 VAC or 30 VDC at 3 A for auxiliary signaling, which supports status indication or interlock functions. Protection is limited to IP20, so the converter is intended for installation inside an enclosure where accidental contact and airborne contamination are controlled.

For demanding motion profiles, the converter permits overload levels of 200 % for 1 second and 150 % for 60 seconds, while start-up torque reaches 150 % at 5 Hz to help move loads from low speed. A speed control span of 1:100 supports steady operation across a broad operating band without losing basic control response. The unit weighs 50.9 kg, has a width of 455 mm in mechanical size 6, and comes without a potentiometer because adjustments are made through the large front panel or the fieldbus. Operation is allowed up to 1000 m above sea level, and the SVPWM modulator supports smooth output generation during continuous industrial duty.
