Product Description:

The FECG02.1-45K0-3P400-A-BN-MODB-01V01 is a frequency converter from Bosch Rexroth Indramat in the FEC Frequency Converters series. It is a second-generation Design 1 unit intended for general automation tasks that require adjustable speed control for three-phase motors. The drive uses V/f control with a built-in PID regulator, accepts a three-phase mains supply, and communicates through a Modbus interface. This control method fits applications where stable motor speed matters more than highly dynamic servo response. Its size 5 housing and large operator panel simplify cabinet integration, while the external brake chopper and the lack of a potentiometer suit systems that use centralized control signals.

The converter’s electrical capacity is rated at 68 kVA of apparent power, allowing it to feed motors that draw up to 101 A on the line side while delivering a continuous output of 95 A. The stated line-side current supports larger motor loads without pushing the converter beyond its continuous operating range. Digital speed commands can be entered with a resolution of 0.01 Hz and a setting tolerance of 0.01%, which supports fine adjustment across the 1:100 control range. Space-vector PWM is used for modulation, and the enclosure has an IP20 protection class for installation inside a ventilated cabinet. The drive can provide 200% for 1 second during short overload events, and operation is permitted at altitudes up to 1000 m. Its chassis width is 364 mm, which helps when planning enclosure spacing around cable routing and ventilation paths.

For longer overload periods, the drive supports 150% for 60 seconds, which helps during extended acceleration or temporary load peaks. The longer overload window is useful for conveyors, mixers, and other loads that may start with higher inertia. The power stage is matched to motors rated at 45 kW and operates on a supply range of 3 AC 380 to 480 V. Despite its large operator panel, the unit has a mass of 33.2 kg, which is manageable for panel installation.
