HDS03.1-W100N-HA20-01-FW
The HDS03.1-W100N-HA20-01-FW is a single-axis controller module supplied by Bosch Rexroth Indramat for machines built around the HDS Drive Controllers series. Within a DIAX04 multi-axis rack, it conditions incoming DC bus energy and regulates the armature current of a connected servo motor, allowing coordinated motion, positioning, and torque control in automated production cells. That arrangement lets the controller serve as the power and regulation stage for one motor axis while relying on the rack for common supply and diagnostic infrastructure. Its rack-mounted format also allows it to operate alongside other axes in systems that use centralized DC bus distribution.
Command signals reach the module through an analog interface, so ±10 V references from a motion card or PLC are converted directly into torque or speed commands without digital protocol overhead. This arrangement suits control systems that use analog command sources instead of serial communication for axis control. A continuous output capacity of 100 A supports medium-to-high power servo motors, while overcurrent monitoring inside the drive helps protect cabling and motor windings. Thermal energy is removed by a built-in internal air blower, so external ducting is not required. The unit is identified as Line 03 within the HDS platform.
The hardware release is Version 1 for this ordering code. The controller exchanges operating data and fault information through the same rack structure used by other modules in the HDS Drive Controllers series, which helps keep system behavior consistent in multi-axis installations. This version uses the connector layout associated with the initial release of this variant, keeping wiring aligned with the module format used in the rack. It is intended for coordinated drive cabinets where shared power supplies, bus rails, and enclosure airflow are managed at the system level.
