Product Description:

The FECG01.2-110K-3P400-A-BN-NNNN-01V01 frequency converter is manufactured by Bosch Rexroth Indramat within the FEC Frequency Converters series. Built for general automation, this first-generation Design 2 unit corresponds to mechanical size 7 and is intended for large control panels. The enclosure is 850 mm high, 570 mm wide, and 360 mm deep, with an assembled mass of 96.5 kg, so the cabinet structure and placement area must accommodate a large drive frame. Its dimensions also suit rear-access panel layouts where front working space needs to be preserved for other equipment.

It handles a three-phase input in the 50 to 60 Hz range and draws a rated input current of 226 A while providing 223 A of continuous output current. The converter delivers 110 kW to the motor terminals and accepts mains from 3 AC 380 to 480 V, which makes it compatible with common industrial power systems. Pulse-width modulation is adjustable from 1 to 6 kHz, allowing a balance between audible motor noise and switching losses. For demanding starts, the drive can produce 150% torque at 5 Hz, so loaded machinery can begin moving from rest with better low-speed pull. Operation is permitted from -10 to +40 °C, and the unit is supplied without a potentiometer, so settings are made through the digital interface.

High-demand duty is supported by an external brake chopper that works with an external resistor to dissipate regenerated energy during deceleration. The inverter can withstand 200% for 1 second or 150% for 60 seconds above nominal load, which supports short overload events without interrupting operation. The housing has an IP20 protection class, so the converter should be installed inside an enclosure for protection against accidental contact and airborne particles. Keeping the braking hardware outside the frame also helps reduce internal heat buildup and leaves more thermal margin inside the converter.
