Product Description:

The FECG02.1-15K0-3P400-A-BN-MODB-01V01 is produced by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. As a variable-speed power stage for general automation, the unit modulates supply voltage to provide adjustable motor speed and torque in material handling, pumping, and conveying applications. This second-generation design includes an integrated brake chopper and a ModBus communication interface, allowing coordinated control with higher-level systems while protecting the DC link during dynamic deceleration. The converter is intended for applications that need controlled acceleration, stable low-speed operation, and consistent response under changing load conditions.

Its electrical frame is classified as mechanical size 3 and is housed in a large panel-format enclosure that measures 275 mm in width, 463 mm in height, and 218 mm in depth, with a total mass of 10.9 kg. The converter delivers a nominal output of 15 kW from three-phase 380 to 480 V AC mains and supports a continuous motor current of 33 A. With a source-side capacity of 25 kVA, it fits within an 80 A upstream fuse range. Closed-loop speed references can be adjusted in steps of 0.01 Hz, while the analog channel maintains an accuracy of ±0.05%. For heavy-duty operation, the power stage can sustain 150 % for 60 seconds without triggering thermal alarms, and the unit is supplied without a potentiometer so setpoints are entered digitally.

During acceleration, the device provides start-up torque of 150 % at 5 Hz, and for transient overloads it can withstand 200 % for 1 second. The closed-loop regulator supports a 1:100 speed control range, allowing precise low-speed operation as well as full-speed production. A rated input current of 42 A matches the thermal limits of the Design 1 circuitry. Protection is limited to IP20, so the converter must be installed inside a ventilated control cabinet. This combination of overload capability, closed-loop control, and cabinet-mounted protection makes the unit suitable for a wide range of industrial drive tasks.
