Product Description:

The FECG01.1-75K0-3P400-A-BN-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. Engineered for general automation, it converts fixed mains power into variable-frequency output so connected motors can follow changing load requirements across conveyors, pumps, and other driven equipment. This method of motor control can reduce unnecessary energy use and lower mechanical stress during routine operation. It is intended for industrial processes that need adjustable motor speed without changing the incoming plant supply.

This device uses a 3-phase input supply in a range of 3 AC 380 to 480 V, and it delivers up to 75 kW of continuous output power. Short-term acceleration demands are supported by an overload capacity of 200% for 1 second, while an external brake chopper dissipates regenerative energy from the DC link during deceleration. The open housing has an IP20 rating, which provides touch protection for internal components during cabinet installation. This first-generation Design 1 unit does not include a potentiometer, so speed commands must come from the host controller. Because the unit lacks a local speed control, setpoint adjustment comes from external automation hardware rather than from the front of the converter.

The converter uses size 6 hardware and an enclosure width of 455 mm, so it requires a large panel space for mounting and airflow clearance. Its wider frame accommodates the power components needed for higher motor loads and the associated thermal path. For extended heavy-load periods, the electronics can withstand 150% for 60 seconds. The power stage is built for the 400 VAC class used in many industrial distribution systems. The cabinet layout should leave room around the heat sink and busbar area to support normal ventilation.
