Rexroth FCS01.1E-W0011-A-04-NNBV – IndraDrive Fc 2.2 kW Frequency Converter
Product Overview
The Rexroth FCS01.1E-W0011-A-04-NNBV is an IndraDrive Fc frequency converter designed for controlling three-phase AC motors in industrial automation and motion applications. Its material number is R911311065. The drive is rated for a 2.2 kW motor at 400 V and supports V/f and sensorless vector control, with an output current capability up to 5.5 A. It accepts a 380-480 V three-phase supply and provides an adjustable 0-400 Hz output-frequency range. The compact IP20 enclosure is intended for installation inside a control cabinet or other protected electrical enclosure. Available documentation also identifies RS232 and RS485 interfaces, along with configurable digital and analog I/O, making the unit suitable for standalone machine control or integration into a broader automation system.

Key Features and Benefits
- Suitable for 2.2 kW, 400 V three-phase motor applications.
- V/f and sensorless vector control support different motor-control strategies.
- 0-400 Hz frequency range provides flexible speed control.
- Short-duration overload capability supports acceleration and transient loads.
- Built-in analog, digital, and relay interfaces reduce the need for additional interface hardware.
- RS232 and RS485 connectivity supports commissioning and system integration.
- DC-bus terminals allow connection within suitable common-bus applications.
- Compact IP20 housing fits protected industrial control cabinets.
Personally, I would verify the motor nameplate and control mode before replacement. Two drives with the same power rating are not automatically interchangeable because motor parameters, braking arrangements, I/O assignments, and communication settings can differ.

Installation and Maintenance
Before installation, verify the incoming three-phase voltage, motor power, rated current, control method, braking requirements, and required acceleration/deceleration parameters. Confirm all existing I/O assignments and communication settings before transferring configuration data.
The unit is IP20 and should therefore be installed inside a suitable electrical cabinet or protected enclosure. Maintain the recommended ventilation clearance above and below the drive, and keep cooling passages free of dust and foreign material. Published installation information recommends approximately 100 mm of clearance above and below the unit.
During maintenance, inspect power terminals, DC-bus connections, cooling fan, control wiring, and RS232/RS485 connections. Allow the DC bus to discharge fully before servicing.
Product Warranty
Warranty coverage depends on supplier, stock condition, and purchase agreement. Confirm whether the unit is new old stock, refurbished, tested used, or surplus, and request the exact hardware revision and test status before procurement.
The Rexroth FCS01.1E-W0011-A-04-NNBV is a compact IndraDrive Fc frequency converter suited to legacy industrial motor-control applications where exact voltage, current, power, and configuration matching are required.
