Product Description:
The FECG01.2-90K0-3P400-A-BN-MODB-01V01 frequency converter is built by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. Designed for general automation, the unit interfaces between the plant’s three-phase supply and an AC motor, adjusting stator frequency to achieve precise speed control. By embedding PID regulation and a field-oriented drive section, it can coordinate pumps, conveyors, and material-handling axes from a central PLC.
At its motor terminals, the converter can deliver 90 kW of mechanical power while operating on the plant’s 400 VAC distribution bus. Continuous output current is rated at 183 A, permitting full-load operation of mid-frame motors without derating. A digital synthesizer sets the output frequency in 0.01 Hz steps, so the controller can issue speed references with very fine resolution for slow-speed positioning or process tuning. Protection against fast transients is provided by an external brake chopper, and the power stage tolerates brief surges up to 200% for 1 second to clear jams or accelerate heavy inertia. Closed-loop PID control is executed in traditional V/F mode, matching voltage to frequency to keep the air-gap flux constant under dynamic load changes.
The mechanical envelope measures 682 mm high, 455 mm wide, and 290 mm deep, yet the frame only weighs 52.5 kg, simplifying panel installation. Once powered, the drive can sustain an overload of 150% for 60 seconds and still hold a speed ratio of 1:100, allowing stable motion from crawl to base speed. Torque buildup at startup is boosted to 150% at 5 Hz, so loaded conveyors begin moving without mechanical clutches. Pulse patterns are generated with Magnetic Flux PWM, a scheme that minimizes motor acoustic noise while reducing switching loss. Communication takes place through the built-in ModBus interface, so parameter updates or alarms can be exchanged with the supervisory system without extra gateways.
