Product Description:

The FECG01.1-55K0-3P400-A-BN-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. As a general-automation drive, it varies output frequency and voltage to regulate motor speed in fans, pumps, conveyors, and similar machinery where process demand changes during operation. It operates on a first-generation control platform that uses Design 1 architecture for this model. The unit relies on an external brake chopper for dynamic braking energy management and is supplied without a potentiometer, so setpoint adjustments are handled through the drive interface or fieldbus.

This converter delivers a rated output of 55 kW, making it suitable for mid-power equipment that needs controlled acceleration and stable running speed. It accepts mains within the 3 AC 380 to 480 V range, while its protection rating of IP20 limits installation to clean, enclosed panels where contact with live internal sections is restricted. During rapid load surges, it can supply 200% for 1 second, which supports high-torque acceleration or brief jam recovery without triggering a fault. The housing width is 364 mm, placing it in the big-size panel category and providing room for larger heat sinks that help maintain thermal limits during overload duty.

The high overload profile is complemented by a sustained reserve of 150% for 60 seconds, allowing extended torque boosts before current limiting or thermal derating becomes necessary. Operating on a 400 VAC voltage class with a balanced 3-phase input, the converter helps keep input loading even across the supply and reduces stress on upstream switchgear. Mechanical Size 5 standardizes the mounting hole pattern and front-panel layout, leaving clear access to the control terminals despite the lack of a manual potentiometer. This operating profile suits variable-torque conveyors and constant-torque mixers that require short burst overloads followed by steady running.
