Product Description:

The FECG01.2-75K0-3P400-A-BN-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. As a frequency converter, it modulates the speed and torque of three-phase induction motors used in general automation. This allows the connected motor to match changing load demands while helping reduce unnecessary energy use during partial-load operation. By varying output frequency and voltage, the unit supports smoother starts and more flexible speed control in equipment such as conveyors, pumps, fans, and other process-driven machinery.

The rated output is 75 kW, so the converter can support that level of continuous motor power without derating under the stated conditions. The input supply window of 3 AC 380 to 480 V in the 400 VAC class allows operation on standard industrial mains while tolerating modest voltage variation. To accommodate dynamic loads, the unit can sustain an overload of 200% for 1 second for sudden acceleration demands and 150% for 60 seconds when elevated torque is needed for a longer interval. A protection category of IP20 provides touch-safe terminals, so the converter is intended for installation inside a cabinet where dust and liquids are controlled.

The converter uses a 3-phase input, so current is drawn symmetrically from the mains and harmonic distortion remains low. Hardware layout follows Design 2 of the first generation, and the power stage works with an external brake chopper to handle regenerative energy during deceleration. Physical integration is guided by Mechanical Size 6 and a cabinet width of 455 mm, which help determine the mounting space required in large enclosures. The unit comes without a potentiometer, so setpoint adjustments are handled through the controller or fieldbus instead of the front panel.
