Product Description:

The FCS01.1E-W0006-A-04-NNBV is a frequency converter manufactured by Bosch Rexroth Indramat for the FCS Frequency Converters series. It accepts three-phase plant power and delivers controlled voltage and frequency to induction motors so automated conveyors, pumps, and material-handling cells can vary speed without mechanical gear changes. Positioned between the line supply and the drive motor, it provides ramped acceleration and regulated torque to match process demands.

This converter is protected to IP20, and its internal blower forces air through the housing for continuous cooling. The unit connects to a 3 × AC 380…480 V network through a three-phase input, corresponds to line 1, and is design version 1. It supplies a linear V/f curve and a rated output of 1.1 kW, letting standard motors run efficiently across the speed range. A maximum output frequency of 400 Hz supports high-speed spindles, while the nominal operating frequency remains at 50 / 60 Hz for conventional machinery. The enclosure stands 226 mm tall, and the mounting dimension L1 is 260 mm, which helps with panel layout in compact cabinets. Brake energy can be routed to an external resistor, and an integrated brake transistor manages that discharge.

The converter operates with a maximum pulse frequency of 16 kHz for fine PWM resolution and a continuous current ceiling of 6 A. The internal DC link is active, and the bus voltage equals 1.41 × mains voltage, providing a stable energy reservoir during regeneration. Short-term overload capability reaches 200% for 5 seconds and 150% for 60 seconds, allowing the drive to handle peak acceleration or shock loads. A 24 V DC auxiliary supply keeps the control electronics alive during mains interruptions, and the feeding power-supply configuration supports common-bus installation across multiple axes.
