Product Description:
The product FCS01.1E-W0003-A-02-NNBV is manufactured by Bosch Rexroth Indramat and belongs to the FCS Frequency Converters series. It is an AC frequency converter that converts fixed single-phase mains power into a variable three-phase output for induction-motor speed control in automated production lines, material-handling devices, and packaging equipment. By adjusting both voltage and frequency, the unit provides a simple interface between the facility supply network and drives that demand programmable shaft speed.
Within the platform hierarchy, the device is classified as design version 1 in line 1 and operates in feeding mode. It accepts a single-phase input of 1 × AC 200…240 V at the nominal 50/60 Hz supply and delivers a continuous mechanical output of 0.25 kW. Motor current can rise to 3 A, while the synthesized output frequency is adjustable up to 400 Hz. Pulse-width modulation is used between 3 kHz and a carrier ceiling of 16 kHz, allowing users to trade switching loss against audible noise. These electrical limits indicate the converter’s compatibility with small induction motors used on auxiliary axes, and they set the operating range for cabling cross-sections, thermal management, and noise filtering at the installation site.
Protective and braking functions complete the design. An external resistor handles regenerated energy, and the integrated transistor can dissipate a steady 0.1 kW of braking power drawn from the intermediate DC link that is accessible through the converter’s coupling terminals. During rapid acceleration, the current ceiling lifts to 200 % for 5 s, then holds at 150 % for 60 s to prevent overtemperature trips. Internal air cooling, provided by an integrated blower, maintains thermal balance while keeping the enclosure compact. The housing carries an IP20 rating, so it must be mounted inside a cabinet but still provides finger-safe access for wiring. A 24 V auxiliary supply supports control logic and energizes the brake transistor, and the intermediate-circuit connection permits energy exchange between adjacent drives.
