Product Description:

The FECG01.1-2K20-3P400-A-SP-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat as part of the FEC Frequency Converters series. Built for general automation installations, it converts fixed three-phase mains power into an adjustable output that lets induction or synchronous motors run at commanded speed and torque. The device sits ahead of a motor drive train, regulating voltage and frequency to match process requirements while lowering mechanical stress during starts and stops. It can be used where stable motor response is needed across changing operating conditions.

Rated at 2.2 kW, the converter handles medium-power axes without additional cooling hardware. It accepts supply lines within 3 AC 380 to 480 V, and the input is 3-phase, enabling balanced current draw and reduced neutral current in plant distribution panels. Its enclosure carries an IP20 protection class that is suitable for installation inside closed electrical cabinets. A width of 125 mm helps keep panel layouts compact, and the mechanical size 1 fits the standard mounting format used for this product line. An internal brake chopper dissipates regenerated energy during rapid deceleration cycles, and a front-mounted potentiometer allows local speed adjustment when direct manual control is needed.

The converter is designed for a 400 VAC class supply and has high overload capacity for short-term demand changes. Output current can rise to 200% for 1 second and remain at 150% for 60 seconds before returning to continuous duty. These overload reserves help the drive absorb temporary torque spikes caused by start-up inertia or abrupt load changes without unnecessary shutdowns. The unit is Design Version 1 of the first generation, and its operating profile suits applications that need short bursts of higher torque during starting or braking.
