HDS03.2-W075N-HA15-01-FW
The HDS03.2-W075N-HA15-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. When mounted in a central rack, it delivers regulated current to connected servo power stages, translating velocity and torque references from the motion processor into precise motor excitation. The module enables coordinated multi-axis motion so packaging, printing, and material-handling equipment can hold commanded positions and repeat cycles accurately. In centralized drive cabinets, this arrangement also allows the controller to operate alongside adjacent modules that share common power distribution and coordinated control tasks.
This unit communicates through an analog command interface, meaning speed or torque references arrive as proportional voltage signals that the controller converts into internal setpoints without digital fieldbus overhead. Because the reference is analog, the controller can respond directly to external control hardware that generates continuous command signals for speed or torque regulation. The device belongs to Line 03, which indicates its mechanical envelope and the slot spacing it requires in a multi-axis rack. Thermal management relies on an integrated internal air blower that directs cooling air across the power electronics. The power stage is rated for 75 A, so the module can drive motors that demand high peak currents during acceleration while maintaining the permitted temperature rise limits.
As part of the DIAX04 architecture, the controller is identified as Version 2. This version aligns its diagnostic codes and parameter ranges with later motion cards in the platform, helping the unit operate consistently within that system generation. Its designation as an HDS Drive Controller confirms that the module carries both closed-loop regulation logic and the power electronics in one housing, simplifying cabinet wiring to the DC bus and mains input. The integrated regulation section adjusts output current in response to operating conditions so the connected axis can remain stable during load changes and repeated motion cycles.
