Product Description:

The HDS03.2-W075N-HA11-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It handles power conversion and closed-loop motion control so connected servo axes can track velocity, torque, and position commands in automated machinery. By adjusting motor current in real time, it helps maintain commanded motion when the axis sees changing inertia or process resistance. Mounted in a single rack slot, the unit bridges the cabinet power bus with upstream PLC or CNC control hardware without consuming excessive panel space. This arrangement supports coordinated axis duties in pick-and-place stations, feeder lines, print registers, and other systems that require synchronized motion across multiple driven sections.

Its continuous output capability is rated at 75 A, which suits mid-range servomotors used in packaging, transfer, and material-handling equipment. Command data reach the unit through an analog interface, so ±10 V or 4–20 mA reference signals can regulate speed or torque without relying on a networked control bus. Heat from the switching devices is removed by a built-in air blower that circulates cabinet air across the heat sink and helps maintain stable internal temperatures during sustained operation. The controller is part of the DIAX04 platform, so it uses the matching mechanical and electrical format of that drive system.

The product is part of Line 03 in this drive family, indicating its design line within the platform. It is Version 2, and the installed parameter set must correspond to that revision for normal operation. The unit provides PWM generation, feedback processing, and protective shutdown functions while drawing bus voltage from a separate supply module rather than from an integrated power section. This layout keeps the controller focused on axis regulation and power delivery to the motor while the system supply hardware remains external. Diagnostic monitoring is included so the drive can react to fault conditions and protect connected components.
