Product Description:

The FECG01.2-0K75-3P400-A-SP-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. Installed between the mains supply and an AC motor, it modulates voltage and frequency so machine builders can match shaft speed to process demands in general automation lines. By combining electronic control and protective monitoring in one compact unit, it replaces mechanical speed-change methods and supports uniform motion across packaging, material-handling, and assembly equipment. It is suited to applications that benefit from adjustable motor speed instead of fixed-speed operation. This arrangement also helps the connected motor respond more smoothly when the load changes during normal use.

Electrical performance includes a continuous rating of 0.75 kW, which suits the converter to small and medium-frame motors. It accepts 3 AC 380 to 480 V input power, and the input must be 3-phase, which helps maintain balanced line loading during operation. Short bursts of load are handled by an overload capacity of 200% for 1 second, while longer acceleration or deceleration events are covered by 150% for 60 seconds. This reserve supports temporary torque demand when the driven load changes quickly, and it helps the control section maintain stable motor response without abrupt speed loss. The converter can therefore handle brief demand peaks without forcing the process to slow unexpectedly.

The converter has an enclosure rating of IP20, so it is intended for installation in clean control cabinets where the heat sink can dissipate heat through normal airflow. Its internal brake chopper directs regenerated energy to an external resistor, which helps prevent DC-link overvoltage during rapid stopping or deceleration. Local speed adjustment is available through a front-mounted control with a potentiometer, allowing basic speed changes without a separate analog command source. The housing has a frontal width of 125 mm, which helps conserve panel space when several drives are mounted in the same enclosure. The front layout keeps basic control access at the unit itself for straightforward operation.
