Product Description:

The FECC01.2T-B-STD-POTI-NNNN frequency converter is manufactured by Bosch Rexroth Indramat within the FEC Frequency Converters series. This unit conditions incoming three-phase power and modulates output frequency so connected AC motors can run at variable speeds for pumping, conveying, or positioning tasks in automated lines. Its control electronics, operator panel, and interface functions are integrated in a single enclosure, allowing direct installation on machinery control cabinets. Local parameter access is available from the front of the unit, so routine adjustments do not require separate external tools.

Electrical compatibility spans 11 to 110 kW, so the panel can be used with converters across that power range while maintaining the same command logic. The operator panel is classified as Design 2, which indicates the second mechanical revision and matches the current mounting cutout pattern. A backlit display shows 4 characters at a time, matching the internal register size used for numeric entry. The screen can switch between Frequency, Current, Params, Faults, which helps with viewing operating values and fault information from the front of the unit. For direction control, the panel accepts a reverse reference of 5 to 0 V, enabling analog signaling from supervisory PLC outputs.

As a 1st generation panel, it uses the earliest FEC command set for compatibility with legacy drives already in service. The front face uses the Big format, leaving room for dedicated Run, Stop, Set, and Func keys, and the Stop key also serves as a fault reset command. Three hierarchical menu levels provide structured access to configuration, monitoring, and alarm handling. The assembly is supplied without a potentiometer, so speed references must come from external sources. Data entry precision is limited to 5 significant digits, matching the internal scaling used for frequency resolution.
