HDS03.2-W075N-HA19-01-FW

The HDS03.2-W075N-HA19-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It works as the power stage for servo axes in automated machinery, converting DC bus energy from a supply module into controlled three-phase output for individual motors. This arrangement lets each axis receive regulated current while the shared supply section manages bus distribution inside the cabinet. Because the power section is separate from the higher-level controller, the unit focuses on accurate motor current delivery and quick response to command changes. Within an Indramat cabinet, it works with communication and feedback modules to provide velocity and position control for packaging lines, printing presses, and material-handling gantries that require coordinated multi-axis motion.

The controller can deliver up to 75 A of continuous motor current, which is the maximum thermal load its power electronics can sustain during normal operation. Command signals enter through an analog interface, so the drive accepts ±10 V speed or torque references from the motion control instead of a fieldbus message. That arrangement also supports retrofit applications that already provide analog speed references from existing machine controls. Internal components are cooled by a built-in air blower, which pulls air across the heat sink and removes the need for external ducting. The unit is part of Line 03, which marks the third design line. It is listed as Version 2, which identifies this product revision.

As part of the DIAX04 platform, the device uses the same general control architecture as other compatible axes in the rack. Its classification as an HDS Drive Controller means it works with separate regeneration, power supply, and safety modules rather than carrying those functions internally. Separate support modules handle shared power functions, while this controller remains dedicated to axis regulation. When paired with a matching supply module, the controller supports closed-loop velocity and position control for demanding servo applications. It is suited for systems that depend on coordinated acceleration, deceleration, and stable axis response under changing load conditions.
