Product Description:

The HDS03.1-W100N-HS11-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Intended for multi-axis automation, the unit links a DC bus to individual servo modules and delivers the velocity and position loops needed in machine tools, material-handling cells, and packaging lines. By combining control electronics and an integrated power stage, it supplies the regulated motor currents that translate program commands into repeatable mechanical motion. This arrangement allows the higher-level control system to coordinate several axes while the drive manages motor response at the machine level. Because the current and motion loops are handled inside the controller, connected motors can react quickly to changing loads and command updates.

The command channel relies on the SERCOS optical interface, enabling deterministic telegram exchange with the motion master. This module belongs to the DIAX04 controller family, so its bus bars, connectors, and mechanical outline align with other drives in the same rack. Heat produced by switching devices is expelled through a built-in internal air blower, eliminating the need for a separate fan tray. The housing has an IP 10 protection category, which provides basic finger protection when the unit is mounted behind a closed panel. The power section supplies a continuous 100 A of output current, allowing the controller to operate large synchronous or induction servo motors at rated torque under nominal conditions. Its rack-compatible layout also supports orderly wiring in compact multi-axis cabinets.

The unit operates in ambient temperatures from +5 ... +45 °C. If interior temperatures rise, it can continue up to +55 °C with reduced current output. During storage or shipment, it withstands climates between -30 ... +85 °C, which helps protect boards and capacitors from thermal stress. Installation is approved for elevations to 1000 m above sea level, where air density still supports the internal blower. Electrical insulation conforms to class C per DIN VDE 0110, and the controller is Version 1 in Line 03.
