Product Description:

The FECG01.2-5K50-3P400-A-SP-MODB-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. It is a first-generation, design 2 unit intended for general automation tasks that require flexible speed and torque control on three-phase motors. In operation, it adjusts motor frequency and voltage so connected equipment can run at the speed required by the process. Its 400 VAC class input matches standard plant distribution, so it can be installed directly in many industrial systems without a step-down transformer. This arrangement supports variable-speed duty in equipment such as fans, conveyors, and process machinery.

It accepts a three-phase mains feed within 3 AC 380 to 480 V, which matches the voltage class assigned to this model. The converter delivers a continuous output of 5.5 kW, making it suitable for pumps, extruders, or conveying drives. Control electronics permit a momentary overload of 200% for 1 second for high-inertia starting, followed by 150% for 60 seconds for longer acceleration or short process peaks. Supervisory integration uses the Modbus interface, so operating parameters and diagnostic data can be exchanged over standard serial wiring. The compact front panel also helps in installations where cabinet depth is limited.

The housing has an IP20 rating, so the unit is intended for installation inside a cabinet. An internal brake chopper routes regenerated energy to an onboard resistor to help prevent DC-bus overvoltage during rapid deceleration. The front panel comes with a potentiometer, allowing local speed adjustment without an added external control device. Even with these features, the housing width remains 220 mm, and mechanical size 2 helps keep the overall depth moderate for side-by-side mounting in narrow racks.
