Product Description:

The HDS03.1-W100N-HA01-01-FW is a drive controller from Bosch Rexroth Indramat that belongs to the HDS Drive Controllers series. The unit regulates servo axes by modulating DC bus power into controlled motor current, enabling coordinated motion in automated assembly lines, packaging stations, and material-handling cells. It serves as the link between higher-level control logic and the electrical drives that perform mechanical work in industrial automation. This allows commanded axis behavior to be translated into regulated current output for repeatable motion.

Command references enter through an analog command interface, so velocity or torque setpoints arrive as scalable voltage signals that the controller translates into precise drive commands. Internal heat is removed by a built-in air blower, which supports thermal management without requiring external cabinet fans. The power stage can deliver up to 100 A of continuous current, which sets the upper limit for the connected motor size. The enclosure has an IP 10 rating, which provides finger-safe access but no dust sealing. Continuous operation is specified within an ambient range of +5 to +45 °C, so the unit can be mounted in most production areas without extra cooling hardware.

The controller is approved for installation heights to 1000 m above sea level, and output must be derated above that altitude. When enclosure temperatures rise, operation can continue up to +55 °C if the load is reduced proportionally. For shipping or warehouse storage, it can withstand temperatures from -30 to +85 °C, which helps protect internal components during transport and long-term warehousing. The windings and internal wiring meet insulation class C under DIN VDE 0110, which provides elevated thermal endurance. The hardware is part of Line 03 and Version 1 in the DIAX04 controller family.
