Product Description:

Bosch Rexroth Indramat manufactures the FECG01.2-75K0-3P400-A-BN-MODB-01V01 in the FEC Frequency Converters series. The unit is a frequency converter that adjusts motor speed for conveyor sections, pumps, and other stations used in general automation. It is a first-generation device with Design 2 construction and relies on an external brake chopper to absorb regenerated energy during quick stops. This arrangement helps prevent overvoltage on the DC link when a driven load decelerates rapidly.

The converter supplies a continuous output of 75 kW, which is the rated power available for connected motor loads under normal operating conditions. It accepts line voltages in the range of 3 AC 380 to 480 V, allowing it to operate from common industrial mains without a separate transformer. A 3-phase input keeps loading balanced across the supply and supports higher power transfer than a comparable single-phase feed. The housing has an IP20 protection rating, so the unit is intended for installation inside an enclosed electrical cabinet. For brief transients, the device tolerates 200% for 1 second above nominal current, which helps during short high-torque events such as the start of high-inertia loads.

Additional overload capacity of 150% for 60 seconds allows longer acceleration ramps or temporary process peaks without immediate thermal shutdown. Data exchange with supervisory controllers is handled through a ModBus interface, which supports communication with PLC and SCADA systems. The internal power stage is rated for the 400 VAC class used in many industrial distribution systems. A cabinet width of 455 mm gives the size 6 frame room for high-capacity bus bars while keeping the enclosure practical for panel installation. The drive is supplied without a potentiometer, so speed references are intended to come from fieldbus commands or other external control signals.
