Product Description:

The FECG01.1-3K70-3P400-A-SP-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. As a converter, it modulates the supply frequency delivered to an AC motor, allowing general automation equipment to vary speed without altering mechanical gearing. The unit belongs to the first generation of the FEC design and is identified as design version 1, which provides a baseline feature set for panel installation in distributed control cabinets. This arrangement supports flexible motor-speed adjustment in machinery where process demands can change during normal operation.

This model operates on a 3-phase supply and is categorized in the 400 VAC voltage class, so the incoming lines must match standard industrial three-phase systems at that nominal level. Its permissible input window is 3 AC 380 to 480 V, allowing the drive to maintain regulation when plant voltage moves across the normal tolerance range. Two short-term overload ratings describe the converter’s current-handling ability: the power stage can supply up to 200% for 1 second to help start high-inertia loads and up to 150% for 60 seconds for longer acceleration periods or brief process disturbances. These margins support temporary torque demand without requiring changes to the basic installation layout. The internal logic, power modules, and field wiring terminals are mounted on a compact panel structure so the unit can fit into enclosures where cabinet space is limited.

The housing carries an IP20 protection class, so the converter is intended for installation inside a closed cabinet to prevent accidental contact with live parts. A small size panel format helps the unit fit into narrow control columns and other space-restricted mounting locations. The converter also supports a high overload capacity operating mode that uses the stated current peaks during demanding motor starts or temporary load increases. Local speed trimming is possible because the front panel is supplied with a potentiometer, allowing direct motor-response checks from the cabinet door. This built-in adjustment method can simplify local testing when an external reference signal is not being used.
