Product Description:

The FECG02.1-30K0-3P400-A-BN-MODB-01V01-S001 is a frequency converter manufactured by Bosch Rexroth Indramat as part of the FEC Frequency Converters series. It is deployed in general automation lines to vary the speed of standard induction motors, matching process demands while reducing mechanical stress and energy use. By translating fixed utility power into a variable frequency and voltage output, the unit provides regulated motor control for conveyors, mixers, and material-handling equipment that require adaptable yet repeatable motion profiles.

This second-generation device delivers a nominal output of 30 kW and supplies up to 60 A of continuous current to the motor terminals. Commanded speed resolution is refined to 0.01 Hz through the digital synthesizer, while a short-term reserve allows 200% for 1 second of overload to absorb rapid acceleration demands. The converter is housed in an IP20 enclosure that measures 574 mm high, 290 mm wide, and 236 mm deep, and it weighs 21.5 kg. It operates on a three-phase 380 to 480 V AC mains supply in the 400 VAC class and relies on V/f control augmented by an internal PID regulator and SVPWM switching. Regenerative energy is dissipated by an external brake chopper, and status data are shown on a 4-digit LED panel on the large front panel. The unit uses Design 1 and mechanical size 4 construction, and rated performance is maintained up to an installation altitude of 1000 m.

In extended duty cycles, the converter sustains 150% for 60 seconds of overload, and the drive section can supply a starting pull of 150% at 5 Hz, allowing heavy loads to break static friction without mechanical gear changes. Once in motion, a programmable speed window of 1:100 is supported, and slip compensation keeps frequency error within 0.05% of the analog reference. All parameters can be accessed over the Modbus interface for communication with PLCs. The unit is approved for operation without a front-mounted potentiometer.
