HDS02.1-W040N-HA21-01-FW
The HDS02.1-W040N-HA21-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It converts the shared DC link voltage in a multi-axis rack into controlled three-phase outputs that govern connected servo motors. Within industrial automation, it acts as the intermediary between a motion control processor and the motor windings, delivering commanded torque and speed so packaging, material-handling, and metal-cutting equipment can achieve repeatable axis movement. This arrangement allows the controller to regulate motor current during acceleration, constant-speed operation, and deceleration on coordinated axes.
The controller exchanges setpoints with the higher-level motion card through an analog command communication interface, so velocity or torque references are delivered as differential voltage signals instead of a fieldbus stream. Because the command path is analog, the unit responds directly to external reference signals generated by the rack control electronics. Thermal regulation is handled by a built-in air blower, meaning cooling air is pulled through the heat sink fins without reliance on cabinet airflow. Within the DIAX04 controller family, this unit is part of Line 02. The continuous output stage can supply up to 40 A of motor current, and the power section monitors phase currents so overload shutdown can occur before semiconductor limits are exceeded.
The drive is Version 1, which identifies the first release of this variant. It is classified as an HDS Drive Controller, so it uses the electrical pinout and mounting format used by this controller type. The unit works with the shared DC bus, feedback cabling, and diagnostic connections used across the platform. It is intended for rack-based servo systems that use a common power section and coordinated motion control across several drive modules.
