Product Description:

The FECG02.1-30K0-3P400-A-BN-MODB-01V01 frequency converter is produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. It belongs to the second generation, uses Design 1, and fits a size 4 frame. Intended for general automation, the unit converts fixed utility power into adjustable motor voltage and frequency so that conveyors and pumps can run at variable speed while matching process demand more closely. A ModBus interface allows parameter access from a PLC, while an external brake chopper supports controlled energy dissipation. The unit is supplied in a large housing and without a potentiometer for local speed setting.

Electrical performance is centered on 30 kW of rated output and a continuous current of 60 A, supplied from a 400 VAC 3-phase utility line. The converter accepts an input range of 380 to 480 V AC at 50/60 Hz with a tolerance of ±5% and regulates motor voltage with open-loop V/f control augmented by space-vector SVPWM. With a speed control range of 1:100, the drive can sustain low-speed accuracy during steady operation. The enclosure meets IP20 protection, so cabinet installation helps avoid contact with live parts while still allowing normal cooling airflow. Physical dimensions are 574 mm high, 290 mm wide, and 236 mm deep, and the mass is 21.5 kg for placement in mid-power inverter compartments.

Dynamic limits include 200 % for 1 second and 150 % for 60 seconds, allowing short torque peaks to pass without tripping. Carrier adjustment from 1 to 8 kHz allows a balance between switching loss and audible noise. During initial acceleration, the converter can raise motor torque to 150 % at 5 Hz, enabling heavy loads to start reliably without an immediate current trip. The high overload capacity is maintained across an operating temperature window of −10 to +40 °C, so derating is unnecessary within that span.
