Product Description:

The HDS03.1-W100N-HS79-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It links the system power supply to servo axes and regulates speed, torque, and position in automated equipment through closed-loop control. By accepting motion commands from a plant PLC, the unit modulates its output stage to deliver controlled current to connected motors. This operating role suits packaging lines, material-handling stations, and multipurpose assembly cells where coordinated axis response and repeatable motion are required throughout the machine cycle. The controller is intended for industrial automation systems that need stable axis behavior under changing load conditions.

Command data enters the controller through the SERCOS fiber-optic interface, so motion parameters update in real time across a deterministic ring with synchronized communication. The power stage can deliver up to 100 A of continuous output current, which supports medium-to-high power servo axes during sustained operation. Thermal stability is maintained by a built-in air blower that directs cabinet air across the heat sink to keep internal components within their normal operating range. This helps maintain predictable performance when the axis remains under continuous torque demand. The unit is part of Line 03, and within the DIAX04 family it operates with compatible system modules in multi-axis installations.

The controller is Version 1 within the HDS Drive Controllers lineup. It installs on a standard mounting rail, which helps keep the module aligned in the cabinet and supports unobstructed airflow through the cooling path. Its connection to the common DC bus supports coordinated power flow between axes during acceleration and braking. Cabinet mounting also allows the controller to sit alongside companion modules in the same drive assembly, keeping the power and control sections grouped in a consistent layout. That arrangement supports compact multi-axis cabinet design without changing the module's cooling direction.
