Product Description:

The FECG01.2-11K0-3P400-A-BN-NNNN-01V01 is a frequency converter built by Bosch Rexroth Indramat for the FEC Frequency Converters series. The device is intended for general automation, where it modulates motor speed by supplying adjustable output frequency derived from the plant’s three-phase mains. It sits in the drive cabinet ahead of induction motors, allowing energy-efficient ramping, positioning, and torque control without mechanical gearing. This arrangement lets the drive adjust acceleration and deceleration electronically, which helps reduce mechanical shock during starts and stops. In many cabinets, it replaces fixed-speed starting methods and gives the motor a wider usable operating range.

It is rated for 11 kW continuous power and accepts a 3-phase supply in the 3 AC 380 to 480 V range assigned to the 400 VAC class. An internal brake chopper dissipates regenerated energy, reducing the need for an external resistor bank on moderate inertia loads. The converter meets IP20, so it must be mounted in a closed electrical cabinet where finger-safe but non-sealed equipment is acceptable. The unit tolerates 200 % for 1 second above nominal current, which supports short acceleration bursts without nuisance trips. Because there is no front-panel potentiometer, all setpoints are entered through the keypad or an external control interface. Size 2 construction also leaves useful room for control and power terminal wiring.

For cyclic duty, the drive sustains 150 % for 60 seconds of overcurrent, which supports heavy conveyor starts or pump unblocking sequences. The enclosure width is 220 mm, so adjacent modules should be arranged to maintain airflow in the cabinet. The product is Design 2 and belongs to the 1st generation. These version details distinguish the unit within the early FEC platform without changing its basic purpose as a cabinet-mounted motor speed controller.
