Product Description:
The FECG01.2-37K0-3P400-A-BN-MODB-01V01 frequency converter is produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. It is a first-generation, Design 2 unit intended for general automation lines that require variable-speed control of induction motors. By converting incoming three-phase power into a regulated output, the drive allows connected equipment to follow a commanded speed without relying on mechanical gear changes or contactor-based switching. This operating method supports smoother motor control in conveyors, fans, pumps, and other industrial machinery.
The drive operates from a three-phase AC supply in the 380 to 480 V range and belongs to the 400 VAC voltage class. It can deliver a continuous output current of 75 A, which corresponds to a motor power rating of 37 kW. For short acceleration demands, it provides an overload capability of 200% for 1 second. Speed adjustment can be made in steps of 0.01 Hz across a 1:100 control range. Motor control is handled through open-loop V/f characteristics with an internal PID regulator, and SVPWM switching helps reduce harmonic distortion in the output waveform. Parameter settings are entered through a 4-digit LED display or through the Modbus interface, and the unit does not include a front-panel potentiometer.
The converter uses size 4 hardware and has a large front panel with a width of 290 mm, while its mass is 22 kg. Its enclosure is rated IP20, so the unit is intended for installation inside a cabinet with forced airflow. For longer overload events, the drive supports 150% for 60 seconds above nominal load. Start-up performance includes 150% at 5 Hz, which helps the motor produce strong low-speed torque during initial movement. Continuous apparent power reaches 55 kVA, and regenerated energy is handled by an external brake chopper. An external braking resistor can also be connected in parallel when additional braking capacity is needed.
