Product Description:

The HDS03.2-W100N-HT29-02-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. Designed for multi-axis automation assemblies, the unit sits between the power supply module and the servo modules it coordinates. It provides closed-loop current and velocity control so linked axes can follow programmed motion profiles with minimal latency. In an automation cell, it serves as the regulation stage that helps synchronized machining, packaging, and material-handling lines keep multiple axes moving together. Because it uses a modular format, the controller can be integrated into larger racks where several drive sections share one system layout.

The command channel uses the SERCOS fiber-optic ring, allowing deterministic cyclic setpoint exchange and real-time diagnostics with the master controller. The unit belongs to the controller family used for the same product generation, so related axes share a common parameter structure. Thermal management is handled by a built-in air blower that draws cabinet air through the heat sink and removes the need for external fans. The controller delivers a continuous output of 100 A, which suits medium-to-large servo motors that require strong acceleration torque. This communication method also supports predictable data timing across the ring during coordinated motion. The unit is part of Line 03, the third design line for this platform.

The controller is Version 2, which adds support for more motion blocks and alarm code handling without changing the main operating platform. It is classified as an HDS Drive Controller, so the supporting software can apply matching parameter masks for current limits, blower monitoring, and SERCOS telegram mapping. Axis modules on the shared backplane reference the DIAX04 profile ID during power-on. That check helps keep startup behavior consistent across the connected modules in the same drive assembly. The profile is used before normal axis operation begins, so the controller and attached modules can enter service under the same system structure.
