Product Description:

The FECG01.2-5K50-3P400-A-SN-NNNN-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat within the FEC Frequency Converters series. For general automation, it converts fixed mains power into variable-frequency, variable-voltage output so induction or synchronous motors can match process demands. This allows connected equipment to adjust motor speed to changing load conditions instead of operating only at line frequency. It is used in variable-speed pump, fan, and conveyor systems.

It operates from a three-phase supply in the 400 VAC class and accepts input at 50/60 Hz. The input range of 3 AC 380 to 480 V allows installation on common plant networks, while the rated motor branch delivers 5.5 kW with a continuous output current of 13 A. Frequency synthesis uses Magnetic Flux PWM with a digital step size of 0.01 Hz, and the inverter can drive loads up to 300 Hz, which supports a speed regulation ratio of 1:100. This control method supports smooth speed adjustment across a broad operating range. Starting torque reaches 150% at 5 Hz, and an internal brake chopper sends surplus energy to the onboard 2000 W braking channel through a minimum 82 Ω resistor. The size 2 hardware is 220 mm wide, uses design version 2 of the first generation, includes an RS485 interface, and does not include a potentiometer.

The converter’s high-overload capability includes an instantaneous reserve of 200 % for 1 second and a sustained margin of 150 % for 60 seconds, which helps during the acceleration of inertia-heavy drives without immediate derating. Apparent power is rated at 9.9 kVA, providing headroom for dynamic current peaks during demanding load changes. The IP20 protection class suits closed electrical cabinets, and the housing is intended for installation inside an enclosure rather than in open machine areas.
