Product Description:

The FECG01.2-0K75-3P400-A-SP-MODB-01V01 is a frequency converter released by Bosch Rexroth Indramat within the FEC Frequency Converters series. As a voltage-source inverter, it modulates three-phase mains power to provide speed-controlled AC output for general automation equipment such as pumps, small conveyors, and positioning axes. It varies output frequency and voltage together, allowing smoother starts and steadier low-speed operation than direct line connection. That approach also helps reduce abrupt current draw during acceleration and routine restarts. By matching motor speed to process demand, the unit can reduce energy use and mechanical wear in factory installations.

This model operates on a three-phase supply and accepts a line input of 3 AC 380 to 480 V, which places it in the 400 VAC voltage class. Its power section is rated at 0.75 kW, making it suitable for small induction motor applications. Two short-term overload modes are built in: the drive can sustain 200% for 1 second to help start high-inertia loads and 150% for 60 seconds to ride through temporary process peaks. An internal brake chopper dissipates regenerated energy during rapid deceleration. A factory-installed potentiometer also allows local adjustment of output frequency when simple manual speed trimming is needed.

The converter uses a compact panel form and a mechanical size 1 frame. A housing width of 125 mm helps it fit dense cabinet layouts, and the IP20 enclosure means it must be mounted inside a control cabinet. Communication with higher-level PLCs is handled through the Modbus interface, enabling parameter access and fault reporting over standard fieldbus wiring. This arrangement lets a central controller read operating values and send commands without separate analog wiring. The unit is design 2 and part of the first-generation platform. The narrow enclosure also leaves more room for adjacent protective and control devices in the cabinet.
