Product Description:

The FECG02.1-37K0-3P400-A-BN-MODB-01V01 is a frequency converter built by Bosch Rexroth Indramat within the FEC Frequency Converters series. Intended for general automation cells, the device synthesizes variable output frequency so induction motors can follow precise speed commands across a 1:100 control range. By altering line frequency, it supports acceleration, steady-state running, and deceleration profiles required by conveyors, mixers, and assorted positioning stages. This allows smoother process control when a machine must ramp loads gently or hold a stable running speed under changing conditions.

Electrically, the converter delivers a nominal output of 37 kW while operating in the 400 VAC class on input lines from 380 to 480 V at 50-60 Hz. It accepts a three-phase supply, draws 83 A, and uses space-vector pulse-width modulation; the setpoint resolution is 0.01 Hz for fine tuning. With SVPWM, smooth torque is maintained even at low speed, enabling 150 percent startup torque at 5 Hz. Regenerated energy is routed to an external brake chopper, and users can assign braking times between 0.1 s and 10.0 s with a DC-brake engagement window from 0 Hz to 60 Hz. High overload capability is paired with Modbus communication, and the unit omits a local potentiometer in favor of digital commands.

Continuous motor current is rated at 75 A, and the inverter will tolerate 200 % for 1 second or 150 % for 60 seconds during transient overloads. Switching frequency is selectable in the 1 to 6 kHz range, allowing a balance between acoustic noise and efficiency inside an enclosure classified as IP20. The housing measures 574 mm in height, 290 mm in width, 236 mm in depth, and weighs 22.0 kg. The unit is mechanical size 4, generation 2, and design version 1, and it has a large front panel for parameter access.
