Product Description:

The FECG02.1-7K50-3P400-A-SP-MODB-01V01-S001 is a frequency converter produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. In general automation lines, it converts a fixed three-phase supply into a variable AC output for induction motors. This allows smooth starting, controlled acceleration, and speed regulation without mechanical gear changes or contactor switching. It is intended for applications that need repeatable motor control from a compact drive package.

Rated for 7.5 kW of motor power, the converter covers medium-duty drives such as pumps and conveyors. Its input window of 3 AC 380 to 480 V aligns with the 400 VAC class, and it can supply a continuous output of 17 A under normal cooling. When extra torque is needed, the inverter can withstand 200% for 1 second, giving headroom for high-inertia starts or momentary blockages. Speed commands entered through the keypad or analog input are processed at a resolution of 0.01 Hz, supporting fine flow or feed adjustments in V/F control mode. Internal brake-chopper circuitry and a connection for an external resistor manage regenerative energy, while an analog frequency-tolerance band of 0.05% helps keep manual references stable.

System integration is simplified by the ModBus interface, allowing PLCs to read status words, set parameters, and issue run commands over a standard serial link. The housing carries a IP20 protection class, so it is intended for cabinet mounting. Its front-mounted potentiometer and compact panel size remain accessible during operation. The size 2 frame weighs 3.5 kg and measures 176 mm in depth, with a width and height of 220 mm, so it fits crowded enclosures. Generation-2 design updates include a secondary overload limit of 150% for 60 seconds, a rated input current of 21 A, and design 1 electronics that stabilize performance without enlarging the footprint.
