Product Description:

The FECG01.1-45K0-3P400-A-BN-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. Classified as Design 1 of the first generation, it converts fixed mains power into variable-frequency output for induction motors used in general automation lines. In operation, it adjusts output frequency and voltage to control the speed of connected motors in common plant processes. The unit uses a mechanical size 5 housing in a big panel format, allowing direct installation in standard control cabinets while keeping wiring runs short for the external brake chopper and braking resistor used with this model.

Electrically, the converter supplies a rated output of 45 kW and a continuous current of 95 A. It accepts a three-phase input of 3 AC 380 to 480 V, which matches the 400 VAC class used on typical plant mains. The enclosure meets IP20, which helps prevent accidental finger contact and requires cabinet installation where dust or fluids may be present. Frequency commands are set in increments of 0.01 Hz, permitting tight speed trimming under V/F control. The drive also uses a 1:100 speed regulation range for low-speed operation, and the external brake chopper with resistor absorbs regenerative energy during deceleration. The unit does not include a potentiometer, so setpoints are intended to arrive digitally from a higher-level controller.

For demanding start-ups, the drive can deliver 150 % at 5 Hz torque, helping it overcome breakaway loads while limiting stator heating. During transient events, it tolerates 200 % for 1 second or 150 % for 60 seconds of overload. Cabinet space must be allocated for the big panel because the front measures 364 mm wide. Adequate side ventilation and busbar clearance should be preserved when the unit is mounted in the cabinet.
