Product Description:

The FECG02.1-90K0-3P400-A-BN-MODB-01V01 frequency converter is manufactured by Bosch Rexroth Indramat and is part of the FEC Frequency Converters series. Positioned between the plant's supply and an induction motor, it reshapes incoming power so that speed and torque can be adjusted on demand. By varying output frequency and voltage, it lets the connected motor match process demand instead of running only at fixed line speed. This capability makes the unit suitable for general automation tasks such as conveyors, packaging machinery, and material-handling stations where precise electrically driven motion is required.

The converter operates in the 400 VAC class and accepts input from 380–480 V AC networks. Its rated output is 90 kW, which is enough to start and regulate sizable pumps or mixers without an auxiliary soft starter. To withstand transient surges, the drive tolerates 200% for 1 second and 150% for 60 seconds of nominal current. This overload capacity helps during motor starting, short acceleration periods, and brief process spikes. The housing has an IP20 protection class, so installation inside a ventilated cabinet is required. Parameter sets and status words are exchanged over the Modbus interface. A size 6 frame provides room for larger heat sinks, and Design 1 identifies the product version used for this model.

The enclosure spans 455 mm in width, which helps align it with standard cabinet rails and leaves room for power and control wiring. The power input is wired for 3-phase mains, and braking energy is directed to an external brake chopper to help manage heat during rapid stops. The converter is a 2nd generation platform and uses a later control design, but it ships without a potentiometer, so operating points must be set through the fieldbus or a remote keypad. This arrangement supports remote adjustment and status monitoring without requiring local analog speed control.
