HDS03.2-W075N-HA27-01-FW
The HDS03.2-W075N-HA27-01-FW belongs to the HDS Drive Controllers series produced by Bosch Rexroth Indramat. As a compact digital drive controller, it links servo axes in the DIAX modular platform to coordinated motion commands while supplying the power-stage control and diagnostic feedback needed for multi-axis industrial automation cells. Within a cabinet, the unit regulates motor torque and speed so that machine tools, material-handling gantries, and packaging stations can run repeatable cycles with tight positional accuracy. Its role is to translate incoming control references into stable motor behavior for synchronized industrial motion.
This controller delivers a rated current of 75 A, enabling it to energize medium-power servo motors without additional amplifiers. Command signals reach the device through an analog interface, which suits legacy PLCs that output ±10 V velocity or torque references. It is part of the DIAX04 family, so it fits common backplane bus bars used in that platform. Thermal management relies on a built-in air blower, which pulls cabinet air across the heat-sink fins during continuous duty. Because cooling air moves through the controller, the enclosure must allow steady airflow around the heat sink area. The unit is part of Line 03, and that designation matches the mechanical dimensions and connector positions used by other third-line HDS modules.
The controller is Version 2, which provides expanded status messaging compared with the initial release. This helps the control system report operating conditions more clearly during normal operation and fault handling. The regulation functions are intended for coordinated multi-axis systems, and the controller can be used alongside drives with different power levels in the same platform. This is useful where several servo axes must exchange status data through a shared control architecture. It also supports stable closed-loop performance in applications that require clear operating feedback.
