Product Description:

The FECC01.1T-B-STD-NNNN-NNNN is a cabinet-mount frequency control unit produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. It converts fixed mains power into a variable-frequency output so automated lines can regulate motor speed in real time. It uses the standard converter product type for variable-frequency drives. The module corresponds to the initial mechanical design for the family and provides direct panel access for viewing electrical parameters at the point of installation. Because it handles speed variation internally, no external chopper or mechanical gearbox is required, which helps reduce noise and component count in the machine.

The unit is Design 1, signaling the baseline circuit layout shared by early units. A front-mounted 4-Digit LED display presents operating data; at power-up the readout defaults to 0.00 Hz, and setpoints can be stepped in precise 0.01 Hz increments through the keypad. The display cycles among frequency, output voltage, and output current so load conditions can be checked without portable instrumentation. To protect settings, the panel returns to its status screen after 2 min of inactivity, helping prevent accidental edits during routine observation. This arrangement keeps common operating values visible while still allowing fine frequency adjustment from the front panel.

Navigation is structured in 3 hierarchical menu levels that separate parameter editing from runtime diagnostics. The large front panel is divided into 2 distinct areas, matching the Big form factor used for this model, so numeric data and status icons remain legible from typical cabinet distances. Parameter entries use 5 significant digits, giving adequate precision for slow-speed conveyors and high-speed spindles alike. This layout keeps frequently viewed operating values separate from editable settings during normal use. The unit is marked as 1st generation, a classification that omits a potentiometer for manual trim and instead relies on a status LED dedicated to rotation and operating-state feedback.
