Product Description:

The FECC01.1T-R-STD-NNNN-NNNN is a compact frequency converter manufactured by Bosch Rexroth Indramat as part of the FEC Frequency Converters series. The unit accepts constant line power and synthesizes a variable-frequency output waveform used for motor speed control, torque trimming, and process synchronization inside automated production cells. By acting as the electrical interface between the supply and the drive stage, it allows local adjustment of acceleration ramps, current limits, and start or stop commands directly from the front panel without additional supervisory hardware.

In the 1st generation release, the converter incorporates a bright LED display that presents operating data through 4 panel digits, while a separate internal register retains five significant positions for parameter accuracy. Operation is guided by four tactile keys, Func, Set, Up, Down, that let users scroll, enter, and store values. For simpler setup, the software is organized into 3 hierarchical menu levels that separate basic setup, process variables, and diagnostic events. A dedicated stop key also serves as the fault-reset function; pressing it clears active trips so the drive can restart without removing mains power or disconnecting field wiring.

The standardized enclosure uses Design 1, which keeps mounting hole positions consistent across compatible models. For local operation, the keypad can supply a speed reference because panel frequency set capability is supported, and an additional mode allows a front-panel panel run/stop command that bypasses remote I/O during troubleshooting. Analog trim is not provided, as the converter ships without a potentiometer, which eliminates drift associated with mechanical knobs. Internally, control algorithms resolve values to 5 significant digits, so fine adjustments entered through the four-digit LED still translate into precise frequency output at the power stage.
