Product Description:

The HDS03.2-W100N-HT73-01-FW drive controller is produced by Bosch Rexroth Indramat and is part of the HDS Drive Controllers series. Installed on a back-plane beside supply and interface modules, it works with a dedicated servo motor to regulate torque, speed, and position. The controller converts incoming motion commands into timed current output so machine axes can follow programmed paths with repeatable accuracy. When paired with the rest of the rack, it serves as the control and power interface between the machine control system and the connected servo axis. This operating role suits machining centers, pick-and-place gantries, and conveyor sections where coordinated axis movement and consistent response to control updates are required throughout the motion cycle.

The controller has a continuous rated current of 100 A, which suits medium-power motors that need stable torque during repeated indexing cycles and sustained motion. Command data and feedback travel through the optical SERCOS interface, giving deterministic communication between the drive and the higher-level control. This communication method supports synchronized motion across multiple drives on the same machine. Heat is removed by a built-in air blower, which keeps airflow localized at the unit and supports cabinet layouts that do not rely on separate cooling ducts. The mechanical dimensions and connector layout follow the DIAX04 standard, so the controller fits the modular arrangement used with related system components.

The unit is in Line 03 of the series and has hardware revision 2. These identifiers distinguish the product revision used for this controller type and separate it from earlier releases with different internal electronics. Version 2 indicates an updated hardware stage with revised gate-driver and diagnostic circuitry for drive monitoring and fault handling. Application-specific drive software is installed as needed for the intended axis function, so the same base controller can be prepared for the required motion task without changing the physical module.
