Product Description:

The FECG01.1-37K0-3P400-A-BN-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. This first-generation, design 1 unit is intended for general automation tasks that require variable-speed control of AC motors. Supplied as a stand-alone controller, it has a high overload capacity that allows the drive to accommodate rapid load changes without derating. By modulating output frequency while tracking input voltage, the device integrates easily into plant mains and supports precise motor torque management on conveyor, pump, and process lines.

Electrically, the converter accepts a supply of 3 AC 380 to 480 V in the 400 VAC class and is wired for 3-phase mains. Its rated output is 37 kW, giving sufficient headroom for medium-power process drives. Under transient loading, it can deliver 200% for 1 second above nominal current, a figure supported by the product’s internal thermal model. For installation, the enclosure carries an IP20 protection class and is supplied in a big panel size, so mounting clearances must allow service access. The unit is supplied without a potentiometer input, so parameter changes are made through the digital interface.

Mechanical integration is simplified by the drive’s Mechanical size 4 housing, which measures 290 mm across the front panel and fits the depth envelopes typical of large control cabinets. Dynamic braking energy is routed to an external brake chopper, preventing excess DC-link voltage during rapid deceleration. For prolonged overload events, the converter sustains 150% for 60 seconds, which supports long acceleration ramps and other high-torque operating periods. The large panel format also leaves room for cable routing and service access inside control cabinets.
