Product Description:
The FCS01.1E-W0005-A-04-NNBV is a variable-frequency converter produced by Bosch Rexroth Indramat for the FCS Frequency Converters series. Delivered as design version 1 on line 1 of the platform, the unit measures 74 mm in width, 186 mm in height, and 153 mm in depth, and it fastens through 5.5 mm mounting holes. Inside its IP20-rated housing, an internal blower moves air across the power electronics so the device can be installed in enclosed control panels. By varying the supply frequency and voltage, the converter allows industrial drives to maintain precise motor speed under changing load conditions. Its compact cabinet format suits installations where drive hardware must fit beside contactors, filters, and I/O modules.
The converter connects directly to a three-phase mains supply of 3 × AC 380–480 V and reshapes that input into an adjustable output that can reach 400.0 Hz. This operating range covers typical induction-motor service as well as high-speed spindle duty. For motors up to 0.75 kW, the inverter can deliver a continuous line current of up to 5 A without exceeding its thermal limits, and the enclosure blocks accidental finger contact but still requires installation in a cabinet for splash protection. By adjusting output frequency and voltage together, the unit can match motor speed to process demand instead of operating only at fixed line frequency. Its power-supply design permits regenerated energy to return to the DC bus through the internal brake transistor during deceleration.
The braking stage handles peaks up to 2.6 kW and can dissipate 0.2 kW continuously with an external resistor. The minimum permitted external resistance is 300 Ω, and a recommended line fuse of 10 A helps limit inrush and fault currents when used with the required system impedance of at least 50 µH per strand. A 24 V DC auxiliary supply maintains the control logic and the integrated brake transistor during mains dropout, so the converter can bring the motor to a controlled stop if line power is interrupted. This keeps the control section active long enough for an orderly shutdown rather than an abrupt coast condition.
