Product Description:

The FECG02.1-37K0-3P400-A-BN-MODB-01V01-S001 frequency converter is produced by Bosch Rexroth Indramat for the second-generation FEC Frequency Converters series. Designed for general automation cells and lines, it translates fixed mains frequency into variable output through a V/F control algorithm so induction motors can match process demands. The converter accepts three-phase input across 3 AC 380 to 480 V, which places it in the 400 VAC class, and it communicates operating data over Modbus.

Rated output power is 37 kW, and the inverter can supply a continuous current of 75 A. A Magnetic Flux PWM stage synthesizes the drive waveform while allowing commands to be adjusted in 0.01 Hz increments, supporting a 1:100 speed regulation range. To handle sudden load spikes, the unit tolerates 200 % for 1 second before returning to nominal output, and the enclosure has an IP20 rating for installation inside a filtered cabinet. A dry relay contact rated 230 VAC or 30 VDC at 3 A is included for status signaling, which gives the control system a simple way to monitor converter state.

The unit has size 4, design 1, and a large front-panel enclosure that measures 290 mm wide, 574 mm high, and 236 mm deep. The chassis weighs 22 kg, so it can usually be mounted in standard cabinets without extra structural support. Start-up torque reaches 150 % at 5 Hz, which helps the drive move loaded motors from low speed with stronger initial pull. The drive can also withstand 150 % for 60 seconds of overload, and it supports an external brake chopper connection for rapid deceleration. An external potentiometer is not provided, so speed references are entered digitally through the onboard large panel keys.
