HDS03.2-W075N-HS70-01-FW
The HDS03.2-W075N-HS70-01-FW is a digital axis drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. It installs in the power section of a DIAX04 multiaxis rack and supplies regulated three-phase output to matched motors for servo or spindle operation. Within an automated cell, the controller closes torque, velocity, and position loops so axes can follow coordinated motion in packaging lines, machine tools, and transfer systems. This arrangement lets the drive regulate current quickly during acceleration, deceleration, and steady-speed operation. It is suited to applications that require synchronized axis behavior and repeatable motion over long production cycles.
Communication with higher-level PLCs or CNCs occurs over the SERCOS fiber-optic interface, giving deterministic data exchange for drive commands and feedback. The power stage is rated for 75 A, so the module can energize medium-to-large synchronous or induction motors during continuous duty. Heat generated by the IGBT stack is removed by a built-in air blower, so no external cooling ducts are required inside the cabinet. As part of the DIAX04 family, the unit shares the rack format used across spindle and servo axes. The unit is part of Line 03 in the series. The optical communication link also helps resist electrical interference from nearby switching devices in the control cabinet.
This module is released as Version 2, which reflects updated control electronics and added diagnostic capability compared with the initial release. It belongs to the HDS Drive Controllers series and works with platform accessories such as auxiliary power supplies, brake relays, and extension cards. The controller can operate as a single-axis node or as part of coordinated groups within the same rack, while maintaining closed-loop motor control for demanding automation tasks. The updated diagnostics can improve status reporting during startup, fault handling, and normal operation. Accessory support also allows the controller to fit into larger drive assemblies without changing the basic rack layout.
