Product Description:

The FECG01.1-5K50-3P400-A-SP-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. As a first-generation, design 1 device, it is used in general automation cells where variable speed control of three-phase induction motors is required. By converting fixed utility frequency to a controlled output, the unit supports precise motor acceleration, controlled braking, and efficient operation on assembly lines, conveyors, and material-handling equipment. Its small panel footprint helps simplify cabinet layout in retrofit projects and other installations with limited space.

The converter accepts a 3-phase supply in the range of 3 AC 380 to 480 V, matching common industrial mains without an upstream transformer. At this input, it delivers a continuous output of 5.5 kW, which is suitable for medium-frame motors used on pumps, fans, conveyors, or indexing tables. An internal brake chopper is built into the power stage so regenerated energy during rapid deceleration can be dissipated safely without added external hardware. When sudden load spikes occur, the inverter can supply 200% for 1 second above its nominal current, which helps the drive ride through brief peak demand. These electrical functions are packaged in mechanical size 2 hardware with a small panel size that measures 220 mm in width.

For extended overload events, the drive sustains 150% for 60 seconds, allowing short periods of extra torque during brief binding or process disturbances. An operator-side speed knob is included, and the unit comes with a potentiometer for manual setpoint adjustment during local operation. Environmental protection is rated IP20, so the converter is protected against accidental contact with internal parts but still requires installation inside an enclosure. Its placement in the 400 VAC class keeps wiring and protective devices consistent with common 400-volt plant systems, and that can simplify integration with existing power distribution.
