HDS03.2-W075N-HT27-02-FW
The HDS03.2-W075N-HT27-02-FW is a drive controller manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series. Within a multi-axis system, it links to a shared supply module and converts the intermediate DC voltage into regulated three-phase power for individual servo or spindle motors. It serves as the axis amplifier in automated equipment, where it regulates motor current in real time so conveyors, pick-and-place units, and machining axes can follow commanded torque and speed profiles. By controlling output from the common DC bus, the unit provides the electrical interface between the power section and the motor windings on each controlled axis.
Communication with the control system takes place over SERCOS, which provides cyclic command exchange and status feedback on a fiber-optic link. Deterministic timing on this interface lets the motion controller send setpoints and receive drive status with minimal delay during coordinated movement. The drive can supply a continuous output current of 75 A, so the connected motor and cabinet cooling arrangement must match that load. Heat from the power stage is removed by a built-in air blower that moves cabinet air through internal channels and across the heat sink surfaces. This cooling method supports stable operation during sustained current demand and helps keep internal temperatures within the intended operating range.
Within the DIAX04 platform, the controller operates with matching system modules and neighboring axes in a shared drive assembly. The unit is assigned to Line 03, which identifies the third design line in this product group, and it is marked Version 2. These identifiers distinguish this controller build within the product line and separate it from earlier coded revisions. The housing format and electrical interfaces follow the established HDS layout, which supports consistent installation across related modules. In rack-based motion systems, this format allows the controller to fit alongside companion units without changing the basic module arrangement.
