Product Description:

The HDS03.1-W100N-HA09-01-FW is a modular drive controller built by Bosch Rexroth Indramat and positioned within the HDS Drive Controllers series. In multi-axis machine tools and automated handling lines, the unit serves as the closed-loop power stage that links DIAX04 system modules to AC servo or spindle motors, regulating torque and speed according to external commands. By converting incoming DC buss energy into controlled three-phase output, the controller enables precise motion profiles, acceleration ramps, and coordinated axis positioning throughout an installation.

Communication with the axis controller is achieved through a ANALOG command interface, allowing simple ±10 V velocity or torque references to be carried on shielded pairs without additional fieldbus hardware. Because the unit belongs to the DIAX04 controller family, parameter structure and peripheral connections are matched to other modules in the same rack, making project interchange straightforward. Thermal management is handled by a Built-in Internal Air Blower, so cabinet designers do not need separate ducting for this drive. The power electronics can deliver a continuous motor current of 100 A, enabling it to operate large synchronous or induction motors on demanding rapid-cycle applications. Hardware design is identified as line 03, which fixes board layout and connector pin-outs for service consistency.

Classified by Bosch Rexroth as an HDS Drive Controller, the device is released in hardware version 1, so firmware and option cards must match this revision for predictable behavior. Because the product list shows None of the alternative variants often found in later releases, stocking and maintenance are simplified. Integration into existing machinery from Bosch Rexroth Indramat is therefore direct, with cable sets, diagnostic tools, and software already aligned to the proven controller format.
