Product Description:
The FCS01.1E-W0003-A-02-NNNBV is a frequency converter manufactured by Bosch Rexroth Indramat within the FCS Frequency Converters series. It serves as a compact power stage that accepts a single-phase supply and produces a variable AC waveform for motor speed regulation in automated production cells, packaging lines, and material-handling equipment. An integrated intermediate circuit and a connection for an external brake resistor support controlled deceleration without overloading the drive section.
The converter is rated for a continuous motor output of 0.25 kW and connects to supply networks of 1 × AC 200–240 V. Speed control is achieved by adjusting the output between 0 and 400 Hz, while carrier modulation can be set from 3 to 16 kHz to balance acoustic noise and switching losses. Motor current is limited to 3 A, which is the maximum permissible load at the stated ambient temperature and cooling conditions. The intermediate circuit charges to a DC-bus voltage equal to the mains RMS voltage multiplied by 1.41. This circuit supplies a stable energy buffer for dynamic torque commands and controlled changes in motor speed.
Short-duty peaks are supported by an overload capacity of 200 % for 5 seconds and a longer-duration capacity of 150 % for 60 seconds, allowing the converter to start high-inertia loads or overcome momentary jams without tripping. The enclosure has an ingress protection rating of IP20, so it must be mounted in a protected cabinet but requires no additional gasketing for basic indoor use. The input accepts voltage variation of up to ±10 % from the nominal value, maintaining stable operation during a line sag or swell. Continuous brake-chopper power is limited to 0.1 kW, allowing braking energy to be directed to a suitable external resistor during deceleration. An integrated blower circulates internal air across the heat-dissipation surfaces to help keep semiconductor junction temperatures within operating limits. The converter supports input frequencies from 47 to 63 Hz, accommodating common industrial power networks without changes to the incoming supply arrangement.
