Product Description:

The FECG01.2-7K50-3P400-A-SN-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. Designed for general automation tasks, this first-generation unit converts fixed mains input into variable motor voltage and frequency so that three-phase induction motors can be speed-controlled inside cabinets. It has mechanical size 2 and is supplied in a small panel format to minimize enclosure footprint. Its purpose is to regulate motor speed in equipment that needs controlled starting, running, and deceleration during normal operation.

The converter’s electrical section is rated at 7.5 kW, which is the maximum continuous shaft power it can deliver to connected motors. It draws a 3-phase supply and accepts line voltages in the range of 3 AC 380 to 480 V, fitting installations built around the 400 VAC class. Internal sensing allows the device to tolerate temporary load surges; it can sustain 200% for 1 second of nominal current for rapid acceleration demands and 150% for 60 seconds for longer overload periods. The housing is rated IP20, which provides finger-safe access and requires installation inside a closed control cabinet. Because the design omits an onboard potentiometer, all speed reference signals must come from the host controller or fieldbus. These overload limits support short acceleration peaks and repeated heavy-duty intervals in variable-speed applications.

As a Design 2 device, the control electronics are mounted behind a faceplate that is only 220 mm wide, allowing tight side-by-side stacking in multi-axis panels. An internal brake chopper is included, so excess regenerative energy can be dissipated without separate external braking hardware. This is useful when decelerating loads return energy during frequent stopping cycles. The small panel format helps conserve cabinet space and leaves more room on the enclosure door for operator-interface components. The layout is suitable for conveyors, indexing tables, and other cyclic loads used in general automation.
