Rexroth IndraDrive Fc
Compact, high-performance
standard frequency converters

Rexroth IndraDrive Fc is the new, high-performance range of converters for open-loop applications. Housed in an ultra-compact book-sized format, four standard frequency converters cover the entire drive range from 0.25 kW to 7.5 kW. IndraDrive Fc is setting new standards in its class with its extensive functions including simple installation, start-up and operation.

Easy installation

The well thought-out design provides user-friendly installation and adjacent positioning of several units. Plug-in control terminals facilitate and speed up installation.

Quick and easy start-up

Simple start-up without the need for a PC is possible due to the intelligent automatic motor identification functionality of the drive.

Using a PC and Rexroth´s start-up software, DriveTop Fc, the drive parameters can be set, documented and saved either offl ine or via the RS232 interface. If using the RS485 connection, simultaneous communication with up to 31 IndraDrive Fcs is possible.

The integrated oscilloscope function assists with optimization of the drive.

Communication on all levels

IndraDrive Fc uses modular function modules to communicate at all automation levels. We supply two plug-in modules for operation without a PC:

• Standard operating module for parameter-oriented operation
• Deluxe operating module with text display in six languages for document-free start-up

The fieldbus interfaces available are PROFIBUS DP, CANopen and DeviceNet.

Maximum plant availability

IndraDrive Fc integrates extensive monitoring functions and an EMC filter. Safe and reliable operation is assured by monitoring sensors controlling the input voltage, output current and motor temperature. Motor operation is safe every time thanks to the integrated brake management function.
