Product Description:

The HDS03.2-W100N-HT11-01-FW is a digital drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. Installed in multi-axis servo cabinets, it regulates armature current and coordinates motion profiles for industrial machinery such as packaging stations and material-handling gantries. By interpreting high-speed command data from upper-level control systems, the unit adjusts motor torque in real time to help maintain position accuracy and throughput. It is suited for cabinet-based drive systems where several axes must respond to centralized motion commands with consistent timing.

Its communication backbone is the SERCOS interface carried over a fiber-optic link, which supports deterministic 2 ms loop times so motion tasks can be synchronized across multiple axes. The optical link also helps reduce susceptibility to electrical noise in cabinets with high switching currents. The power stage is rated for a continuous output of 100 A, which is the maximum RMS motor winding current the controller can supply without overheating. Thermal management relies on a built-in internal air blower that directs cabinet air through heat sink channels and removes heat without external fans. The controller belongs to the DIAX04 family, so it shares connector layout and diagnostics with other units in that platform. The product is part of Line 03, which identifies the third design line.

The controller is Version 2. It mounts on the existing backplane bus without rewiring, so established wiring layouts can remain in place when the unit is integrated into a compatible rack. Internal diagnostics issue LED codes that correspond to fixed error classes, allowing cabling, overcurrent, or temperature faults to be identified quickly. Status information is available directly on the drive front, which helps narrow the source of a shutdown or motion interruption during startup and routine service.
