Product Description:
The HDS03.2-W100N-HS74-01-FW is a drive controller module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It regulates power and motion for synchronous servo axes in centralized multi-axis systems. By converting energy from a shared DC bus into controlled three-phase output, the unit supports precise positioning, contouring, and process synchronization in automated assembly lines, machining centers, and material-handling cells. In these systems, the controller serves as the power stage between the DC bus and the connected motor, so the higher-level control can maintain synchronized axis behavior during production. It is intended for applications where several axes operate from common power hardware and must respond to coordinated motion commands without losing torque or speed control.
The unit exchanges setpoint, status, and diagnostic data over the SERCOS optical ring, so the motion control CPU can command it through a deterministic command interface. Continuous operation is supported by a built-in air blower that circulates cabinet air across the heat sink instead of relying on external ducting. The drive can deliver up to 100 A of output current, allowing it to energize large MKD and MHD servo motors without derating. This arrangement supports stable current delivery during acceleration, constant-speed travel, and rapid changes in axis demand. Protection on the shared DC bus also supports controlled handling of deceleration energy and coordinated branch-circuit protection.
The controller belongs to the DIAX04 automation platform, where axes are organized through a backplane bus in a common drive assembly. Within that architecture, Line 03 identifies the hardware layout and connector style of this model. The controller is Version 2. The HS74 code in the model number indicates the command section used by this unit, which helps distinguish it from similar units in the same product line. Axes on this platform share a common module arrangement, so the controller fits systems built around the DIAX04 drive structure.
