Product Description:

The HDS03.2-W100N-HT27-02-FW is a modular axis drive controller in the HDS Drive Controllers series from Bosch Rexroth Indramat. As part of this multi-axis platform, the unit supplies closed-loop regulation for brushless servo and main-spindle motors used in machine tools, packaging lines, and material-handling systems. It mounts in a DIAX04 drive rack so power, control, and diagnostic buses are consolidated in one assembly. This arrangement supports coordinated motion across several axes while allowing each motor channel to respond to torque, speed, and position commands from a higher-level motion processor. Because the controller is rack-mounted, cabling between companion modules stays concentrated inside the drive assembly rather than being spread across the cabinet.

The controller exchanges setpoint and feedback data with the motion processor over the SERCOS fiber-optic interface, enabling deterministic communication at 2, 4, or 8 Mbaud while keeping the drive galvanically isolated from the control rack. At the power stage, the device is rated for 100 A of continuous motor current. Cooling is handled by a built-in air blower, so the cabinet only needs a clear airflow path rather than external heat sinks or liquid loops. That airflow method simplifies enclosure planning where several axes are stacked in the same cabinet section. The unit belongs to line 03 in the series and is Version 2, identifying the product generation used for this controller.

Within the DIAX04 platform, the unit is classified as an HDS Drive Controller, so it provides the axis-specific regulation layer while sharing a common DC bus with HVE and TVM supply modules. This layout keeps multiple drives organized in the same rack and supports synchronized operation in complex machinery. The controller uses a programming model and diagnostic display consistent with other units in the HDS Drive Controllers series. That consistency keeps status messages and operating behavior uniform across the installation.
