Product Description:
The FCS01.1E-W0025-A-04-NNBV is a frequency converter manufactured by Bosch Rexroth Indramat within the FCS Frequency Converters series. It forms the power interface between a three-phase mains bus and an AC motor, enabling speed and torque regulation for conveyors, pumps, and positioning axes in automated cells. Integrated DC-link circuitry accepts rectified supply energy and modulates it through insulated-gate transistors, placing the unit in the power path of cabinet-mounted drive systems. This arrangement allows the converter to adjust motor output in response to process demands without requiring a separate speed control stage.
Rated power for continuous motor operation is 5.5 kW, which matches medium-frame induction machines used in packaging or material-handling lines. The converter is fed from 3 x AC 380...480 V across three phases, and its internal rectifier raises this to an intermediate-circuit potential of DC mains ×1.41 for pulse-width modulation. Peak output current reaches 25 A, allowing short acceleration bursts before thermal limits intervene. The carrier frequency is 16 kHz, and the synthesized output fundamental can be varied up to 400 Hz. Internal air cooling uses an integrated blower, and the intermediate-circuit terminal supports common-bus installations inside a control cabinet.
For deceleration tasks, the unit incorporates a brake transistor and a 24 V logic supply; this hardware channels regenerated energy into resistors that can dissipate 0.6 kW continuously and up to 8.6 kW in short bursts. The converter also permits an overload of 200% for 5 seconds and 150% for 60 seconds, which supports temporary high-demand operation without exceeding its intended limits. The device is design version 1 and line 1 in the product family. It uses a feeding power supply configuration intended for installation in a control cabinet. This layout suits enclosed industrial drive systems where the converter shares space with contactors, protection devices, and other motion-control hardware.
