Product Description:

The FECG01.2-22K0-3P400-A-BN-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. It serves as a motor-supply interface in general automation, adjusting line frequency and voltage so AC motors can start, stop, and run at commanded speeds while maintaining torque control. Through this role, the device replaces mechanical throttling methods and supports tighter process regulation in conveyor lines, pumps, and material-handling equipment. By varying output frequency instead of relying on mechanical restriction, it can support smoother starts and more stable process response during normal operation.

This model is rated at 22 kW and belongs to the 400 VAC class, accepting input over a span of 3 AC 380 to 480 V. It is engineered for a 3-phase mains network, a configuration that minimizes current ripple and balances load across supply conductors. The converter carries an IP20 protection class, so it must be installed inside a control cabinet to shield it from dust and incidental contact. Mechanical size 3 and the large panel format provide mounting space for power terminals and control wiring, while the first-generation platform and Design 2 designation indicate the product revision. Because the unit is supplied without a potentiometer, speed reference must come from an external analog or fieldbus signal, which keeps speed control available from a remote source. External command signals also allow the operating reference to be set by a supervisory controller or another machine-level interface.

High overload capability is delivered through two short-term ratings: the inverter can tolerate 200% for 1 second to handle rapid acceleration spikes and 150% for 60 seconds for extended but temporary load increases. Excess regenerative energy is routed to an external brake chopper, keeping the DC link voltage within limits during rapid deceleration. This arrangement is useful on applications with frequent slowing cycles, where returned motor energy can raise bus voltage quickly. Cabinet layout is influenced by the housing width of 275 mm, and the large panel size eases access to control, relay, and encoder connectors without crowding adjacent equipment.
