Product Description:
The FCS01.1E-W0011-A-02-NNBV frequency converter is manufactured by Bosch Rexroth Indramat as part of the FCS Frequency Converters series. It converts single-phase supply power into a variable three-phase output so a motor can be accelerated, decelerated, or held at zero speed under closed-loop control. The unit is intended for factory automation applications where adjustable speed control helps match conveyor, pump, or fan torque to changing process demand while supporting controlled braking.
Electrically, the converter accepts a single-phase mains connection of 200–240 V AC with an input frequency range of 47–63 Hz. Internally, a rectifier charges the DC link to the mains voltage multiplied by 1.41, and an IGBT bridge supplies an output frequency from 0 to 400 Hz to the motor. Nominal power handling is 1.1 kW, and the current limit is 11 A. Air drawn through the integrated blower cools the power stage, so no external ducting is required. Frame size B, design version 1, and line 1 identify the unit’s format within the product line, and a line-fed power-supply configuration simplifies cabinet wiring. A 24 V DC auxiliary supply keeps the control electronics active, while the embedded brake transistor directs excess energy to an external resistor during dynamic stopping.
For transient loads, the drive delivers 200% of rated current for 5 seconds or 150% for 60 seconds. Carrier modulation can be set from 3 kHz up to 16 kHz, allowing a balance between switching losses and audible noise. The housing has a protection rating of IP20, so it must be installed inside a closed electrical cabinet while still allowing straightforward access for wiring. Because the output frequency can ramp down to 0 Hz, the converter can provide controlled holding torque without a mechanical brake, and an external braking resistor completes the deceleration circuit.
