Product Description:

The FECG02.1-11K0-3P400-A-BN-MODB-01V01 frequency converter is produced by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. It regulates the speed of three-phase induction motors in general automation lines. This second-generation unit uses Design 1, includes an internal brake chopper, and performs motor control with a PID algorithm while switching through space-vector PWM. The internal brake chopper dissipates regenerated energy during deceleration, which helps the converter manage stopping events within the drive. Communication with higher-level controls is established over the Modbus interface, and because it is supplied without a potentiometer, commands are entered digitally through the large front-panel keypad.

The converter delivers a continuous output of 11 kW from a 3 AC 380 to 480 V mains supply in the 400 VAC class. On the supply side, it draws 30 A, and it feeds the motor with a steady 24 A. This arrangement separates line demand from controlled motor current at the output stage. Closed-loop resolution is supported by a digital frequency step of 0.01 Hz, while analog commands remain within a tolerance of 0.05%. Speed can be adjusted across a 1:100 range, and the drive sustains 150% torque at 5 Hz during startup, which helps maintain controlled low-speed operation under changing load conditions.

The drive supports short-term overloads of 200% for 1 second and 150% for 60 seconds. These overload limits are handled within an IP20 ventilated enclosure, and the ventilated design supports heat removal during sustained operation. The enclosure measures 392 mm tall, 220 mm wide, and 218 mm deep, with a mass of 10.7 kg, and it is listed as mechanical size 2. Its dimensions fit standard control cabinets while still allowing airflow clearance around the unit.
