HDS03.2-W100N-HA20-01-FW
The HDS03.2-W100N-HA20-01-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. As a central axis module, it conditions command signals and supplies regulated power to servo and main spindle drives in multi-axis automation racks. By controlling motor torque and speed in real time, the unit supports precise positioning and synchronized motion in machine tools, printing presses, and handling systems. In these applications, it helps axes respond quickly to reference changes while maintaining stable motion over repeated production cycles.
Command data enter the module through an ANALOG interface, allowing proportional reference voltages from a PLC or motion card to control velocity and torque loops without digital fieldbus hardware. The controller belongs to the DIAX04 family, so its mounting dimensions and backplane connectors match other axes used on that platform. Thermal management is handled by a built-in air blower, which moves cabinet air across the heat sink to keep internal components within their operating range during continuous use. Electrically, the unit can deliver a continuous output of 100 A, giving it the current capacity needed for medium-power motors on feed axes and auxiliary spindles where stable current delivery is needed during acceleration and load changes.
The unit is part of Line 03, which indicates the third design line for this controller type. It is built as Version 2, so the hardware follows the second release baseline. This revision keeps the control layout aligned with established rack architecture and preserves compatibility with related modules that share the same platform. The internal arrangement supports orderly signal flow between the command stage and the power stage, which is important when several axes operate together under changing load conditions.
