Product Description:

The HDS03.2-W100N-HS33-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. As a digital axis module, it integrates into multi-axis drive racks and works with connected servo motors in coordinated motion systems. The unit uses encoder feedback from the motor to regulate position, speed, and torque during operation. This supports closed-loop control so machine motion stays aligned with commanded process sequences. It can also relay motion-related status information to higher-level PLCs that supervise the overall machine cycle. That role makes the controller a central part of coordinated axis behavior in automated equipment.

Communication to the supervisory motion controller is handled through SERCOS, a fiber-optic bus that carries real-time setpoints and status data while supporting deterministic cycle times. Inside the rack, the unit is part of the DIAX04 family, so it fits the same system platform used by companion drive modules. Cooling is provided by a built-in internal air blower that moves air across the heat sink surfaces without external ducting. This airflow helps control semiconductor temperature even when cabinet airflow is limited. The cooling arrangement supports rack installations where space is tight and external air routing is not preferred.

The controller belongs to Line 03 and is released as Version 2. Its power section is rated for a continuous motor current of 100 A, which suits large torque demands on high-inertia axes. In multi-axis applications, that current capacity supports sustained servo output under continuous operating conditions. The version identifier keeps the controller associated with the correct build level within the series. This information helps keep the unit aligned with the intended rack configuration.
