Product Description:

The HDS03.2-W100N-HS04-02-FW is an axis drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It serves as the power and regulation module in DIAX racks, shaping current and velocity loops so servo and spindle motors follow commanded motion during automated cutting, packaging, and assembly routines. By converting shared DC-bus power into controlled motor output, the unit helps each axis maintain stable speed and positioning accuracy when load conditions change. The controller is intended for applications where repeatable torque delivery and closed-loop regulation are required across several axes in the same machine frame.

Electrical delivery is sized for a continuous output of 100 A, so the controller can energize large-torque motors without external boosters. Communication with the higher-level CNC or PLC takes place over the SERCOS fiber-optic ring, enabling deterministic command transfer and parameter exchange at high speed. As part of the DIAX04 platform, the unit uses the module interfaces shared by related rack components. Heat generated by the power semiconductors is removed by a built-in air blower, allowing cabinet mounting without liquid-cooling auxiliaries. The controller is part of Line 03, which identifies its design line for mechanical layout and connector placement.

The unit is Version 2. It provides the position-control slot in a multi-axis arrangement, allowing neighboring modules to share power and feedback buses across the rack. Standardized module widths and sealed airflow paths help it fit established cabinet layouts while directing cooling air through the housing. The controller works with supply modules, motor encoders, and safety relays so servo loops can be closed without a separate amplifier stage. That structure supports compact cabinet organization and keeps signal routing consistent from one axis position to the next.
