Product Description:

The FECC01.2T-B-STD-NNNN-NNNN frequency converter is produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. In automated machinery, this unit modulates the supply frequency delivered to induction motors so that line speed, pump output, or conveyor throughput can be matched to process demand without mechanical gear changes. By adjusting voltage and frequency together, it helps maintain steady torque across the operating speed range, and its compact enclosure is intended for cabinet installation where quick operator interaction is required.

The converter belongs to Design 2. Status and parameter information are shown on a LED panel that can present up to 5 significant digits. The display window contains 4 digits, so longer numeric values scroll through the field when needed. The screen can cycle between frequency, motor current, adjustable parameters, and active fault codes. Navigation and value entry are performed with a membrane keyboard that provides 6 keys for start, stop, increment, decrement, escape, and store functions, allowing adjustment without an external console.

User interaction is structured through 3 menu levels, separating real-time operating data from protected setup fields. Because the power section and control board share an integrated mounting style, no separate keypad module or display cable is required, which simplifies panel wiring and reduces depth inside the cabinet. The unit is part of the 1st generation of FEC controls, so its command structure matches early Rexroth drive platforms used on analog reference networks. Speed trimming is handled through digital inputs because the converter is supplied without a potentiometer. This arrangement avoids drift from mechanical adjusters and supports remote setpoint control from the PLC.
