Product Description:

The HDS03.2-W075N-HS68-01-FW is a single-axis drive controller manufactured by Bosch Rexroth Indramat. Installed inside multi-axis cabinets, the module serves as the closed-loop power stage between a motion control CPU and a synchronous or asynchronous motor. It receives velocity or torque commands, reads current and position feedback, and adjusts output pulses so the connected axis follows the required motion profile in machining centers, handling gantries, and packaging equipment. This operating role allows one controller to manage the electrical output for one motorized axis while the higher-level control coordinates the rest of the machine during acceleration, deceleration, and steady running.

The unit communicates over SERCOS, a fiber-optic interface that transmits setpoints and diagnostic data in deterministic cycles for coordinated motion. This communication method supports precise timing when several axes must move in step or hold a synchronized speed relationship. A continuous output capability of 75 A indicates the motor phase current it can supply without thermal cutback during normal operation. Heat generated in the power section is removed by a built-in air blower, allowing dense mounting without separate external fans. The controller belongs to the DIAX04 platform, and the designation Line 03 identifies the applicable design line for the module.

The unit is Version 2. It is part of the HDS Drive Controllers series and is compatible with standard power supplies and backplane connectors used in matching cabinets. This arrangement supports installation in systems that use the same electrical interface and module layout. The compact plug-in format suits cabinet designs where drive sections are grouped closely together in coordinated motion systems. Its function remains focused on regulated motor control rather than onboard machine logic, which stays in the higher-level control system.
