Product Description:

The FECG01.2-19K0-3P400-A-BN-MODB-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. Intended for general automation, it varies three-phase motor speed by applying V/f control curves that are shaped through a built-in PID controller. The unit belongs to the 1st generation and is identified as Design 2 within the series, placing it among early models that use space-vector pulse-width modulation (SVPWM) to synthesize the output waveform from a 400 VAC supply.

The converter accepts a line supply of 3 AC 380 to 480 V and is rated to the protection class IP20, so it must be installed inside a cabinet to avoid contact with live parts. A digital frequency resolution of 0.01 Hz allows fine incremental speed commands across its 1:100 control range, while analog setpoints are followed with only 0.05 % tolerance. Start-up torque reaches 150 % at 5 Hz, useful for conveyors or mixers that need high break-away force. High overload capacity is confirmed by two limits: the inverter can deliver 200% for 1 second to handle abrupt jams and 150% for 60 seconds for prolonged surges. The interface is ModBus, enabling simple networked parameter access, and the front panel is supplied in the big size format, though no potentiometer is fitted for local speed trim.

Mechanical data back up the electrical profile. The enclosure weighs 16.2 kg, a mass that assists thermal inertia when the heatsink is challenged by repeated overloads. Overall height is 463 mm, width is 275 mm, and depth is 218 mm, dimensions that must be considered when planning cabinet space and airflow paths. Three-phase input terminals are grouped on the lower edge, and the ModBus port is isolated on a separate header to reduce electromagnetic interference with SVPWM switching. Because the unit is delivered without a potentiometer, any manual speed demand must be applied through an external analog source or through network commands that respect the 0.05 % setting accuracy.
