Product Description:

The Bosch Rexroth Indramat FECG01.1-280K-3P400-A-BN-NNNN-01V01 is part of the FEC Frequency Converters series and is intended to vary motor speed in general automation lines. By converting the fixed mains frequency to a controlled output, the device lets drives accelerate smoothly, hold intermediate speeds, or decelerate under program control. This controlled output helps reduce abrupt speed changes that can disturb product handling or synchronized machine timing. Its role within packaging, material-handling, and assembly systems is to supply the commanded frequency and voltage profile so that connected three-phase motors follow precise motion sequences.

This converter accepts a 3-phase supply within 3 AC 380 to 480 V, classified internally as 400 VAC. Within that envelope, the control section monitors current and permits temporary surges to 200% for 1 second to overcome starting inertia, and to 150% for 60 seconds for extended load peaks without tripping. These overload windows are managed by the control section so torque reserves are available while semiconductor temperatures remain within safe limits. The wide input range supports use on common industrial power systems without changing the basic control behavior. Operating on an industrial power bus, the unit matches the dynamics of hoists, extruders, or indexing tables that demand a short burst of extra current and then return quickly to nominal loading.

Mechanical integration uses the Big size front panel, which provides additional surface area for airflow through the slotted grilles of the IP20 housing. The enclosure rating restricts installation to closed cabinets, where accidental contact and falling debris are limited. Parameter adjustment is carried out solely through the digital interface, and the unit is supplied without a potentiometer, which reduces analog drift and keeps local manual adjustment out of the design. Because local analog adjustment is omitted, speed references are entered through the digital control path rather than from a front-mounted knob. The unit has High overload capacity, allowing short overload periods while temperature-based derating protects internal components.
