Rexroth IndraDrive Delivers Power at Low Cost

May 21, 2010

Featuring a compact space-saving design and open support of SERCOS III communication bus, the Rexroth IndraDrive Cs Economy low-power servo drive provides a cost-effective drive platform that delivers the appropriate amount of functionality.

The IndraDrive Cs Economy is suitable for industries ranging from packaging, semiconductor and medical, to printing, converting, machine tool and metal forming for small-size applications in a low power range.

The drive is designed to be flexible and deliver just the right amount of power at a lower cost. It has a multi-encoder interface that supports Hiperface, EnDat 2.1 and 2.2, 1Vss, 5 V TTL and Rexroth MSM and MSK servo motors

The IndraDrive Cs Economy is part of the Rexroth advanced automation platform that supports the SERCOS III interface for connecting machines, controls, drives, I/O, safety and HMI that helps to lower the controls cost and simplify integration for OEMs, systems integrators and end users.

The drive can be equipped with safety-on-board features, such as Safe Torque Off and Safe Brake Control for certifiable drive-based machine safety. This eliminates the need for separate safety components.

The Economy version of the IndraDrive Cs comes with digital inputs and outputs plus an analog input on board, integrated brake resistor and an intelligent operation panel with programming module function. For users that require more power or additional protocols, Rexroth offers a Universal model of the IndraDrive Cs.

With dimensions measuring 50 x 215 x 196 mm for one unit and 70 x 268 x 196 mm for the larger unit, the IndraDrive Cs is available in models ranging from 50 W up to 3.5 kW. Maximum current ranges from 3 A up to 28 A, with a high overload range. This size range is optimal for packaging applications.

The IndraDrive Cs platform includes Rexroth MSM and MSK series AC servo motors ranging from 50 W up to 3.5 kW continuous power with IP 54 protection (MSM) or IP 65 protection (MSK), multi-turn absolute encoder functionality and optional holding brake.
