HDS03.1-W100N-HT12-01-FW
The HDS03.1-W100N-HT12-01-FW is a modular axis drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. It supplies regulated power to servo or main-spindle drives, coordinating motion cycles in CNC machines, printing presses, and handling equipment. By converting logic-level commands into controlled current for the attached power section, the unit forms a closed-loop actuator channel that simplifies installation in distributed automation cells. It is intended for applications that require coordinated torque and speed control across multiple machine axes. The modular format also allows the control section to be paired with a compatible power stage sized for the motor load.
Its command channel is based on the SERCOS fiber-optic interface, so parameter data and real-time setpoints move across a deterministic serial ring without discrete analog wiring. The controller belongs to the DIAX04 platform, meaning it occupies a standardized slot in the common backplane and shares architecture with adjacent axes. A continuous output of 100 A is available, allowing the module to drive high-torque motors during acceleration without external booster cards. Thermal control relies on a built-in air blower, which moves cabinet air through the heat-sink fins rather than requiring ducted cooling. Within the product coding, it is tagged as Line 03. This arrangement helps maintain stable command transmission in electrically noisy industrial cabinets.
The unit is released as Version 1, which identifies the first build of this model. Its role in the drive stack is the control section of a two-card axis, so control tasks remain separate from the power module. Inside the enclosure, diagnostic LEDs, address switches, and fiber-optic connectors follow the layout used on this product line. These interface elements provide status indication and communication access during normal machine operation. The layout also supports clear visual monitoring of operating states while the drive is in service.
