Product Description:

The FECG01.2-15K0-3P400-A-BN-MODB-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. It serves as an intermediary between a three-phase supply and an induction motor, allowing automated machinery to run at application-specific speeds by modulating output frequency. The unit targets general automation tasks and includes an internal brake chopper, so regenerative energy can be dissipated without external resistors. Three analog inputs, eight digital inputs, two analog outputs, and a Modbus interface give host controllers multiple ways to issue speed or torque commands and read process variables.

This converter is rated for an output of 15 kW, enabling mid-range pumps, conveyors, or mixers to start and run from a single enclosure. It draws power from grids within 3 AC 380 to 480 V, matching the common 400 VAC class used in industrial plants. Under continuous operation, the input side may carry 42 A, while the inverter section delivers 33 A to the motor; these current limits help determine fuse sizing and cable selection. A magnetic flux PWM stage executes the chosen control scheme, and its selectable mode is V/F, which keeps the voltage-to-frequency ratio constant so motor flux stays near nominal across the operating range.

When loads surge, the drive can momentarily supply up to 200% for 1 second or sustain 150% for 60 seconds without tripping; this overload capacity complements the start-up torque of 150% at 5 Hz, allowing loaded shafts to break static friction at low speed. Once running, the speed range covers a 1:100 window, giving fine adjustment from creeping jogs to full-rate throughput. Its IP20 housing, 275 mm panel width, 10.9 kg mass, and size 3 frame help with cabinet layout, while a built-in relay rated 250 VAC/30 VDC at 3 A can forward operating states to external interlocks or alarms.
