Product Description:

The Bosch Rexroth Indramat FECG02.1-22K0-3P400-A-BN-MODB-01V01-S001 belongs to the FEC Frequency Converters series and is supplied as a frequency converter for general automation. It is a three-phase device in design version 1 and belongs to the second generation of the family. It interfaces with controllers through Modbus on an RS-485 link. Its task is to convert process commands into adjustable voltage and frequency for induction motors in the 400 V class, supporting pumps, fans, and conveyors where variable speed is required. It is suited to applications that need repeatable speed changes across varying process loads.

Rated output is 22 kW, and apparent power capability is 34 kVA. The unit accepts three-phase 380 to 480 V mains in the 400 VAC class and draws a full-load current of 51 A. Vector-free regulation uses a V/F algorithm with SVPWM, and frequency commands can be set with a digital resolution of 0.01 Hz. Three analog inputs, two analog outputs, and eight digital inputs connect field signals, while analog setpoints maintain a 0.05% tolerance. A single RS-485 port centralizes communication, and the lack of an onboard potentiometer means speed references are entered from the host controller. The big-panel enclosure is 275 mm wide, uses mechanical size 3 construction, and includes an external brake chopper for cabinet-based installations.

Two overload bands are available, including 150 % for 60 s for sustained short-term demand. The converter also provides 150 % at 5 Hz starting torque, which helps move loaded motors from low speed without oversizing. The enclosure has an IP20 rating for ventilated cabinets, and the unit weighs 16.9 kg. An external brake chopper handles regenerated energy during rapid deceleration, while the SVPWM inverter maintains stable output waveforms during continuous duty within the allowed input range.
