HDS03.1-W075N-HS91-01-FW Bosch Rexroth Indramat

Product Description:

The HDS03.1-W075N-HS91-01-FW is a digital drive controller produced by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. As an axis module, it receives set-point data from higher-level motion systems and modulates power to connected servo drives. Within an automated cell it coordinates acceleration, deceleration, and holding functions, allowing precise multi-axis positioning without mechanical relays. Integrated diagnostics and parameter memory reduce commissioning time and support quick replacement, making the unit a central component in material handling lines, robotics joints, and packaging machinery.

At its power stage the controller can deliver up to 75 A of continuous output current, so motor windings that demand high peak torque can be driven without external boosters. Command data move over the SERCOS fibre-optic ring, permitting deterministic telegram cycles and galvanic isolation from noisy plant grounds. Membership in the DIAX04 controller family ensures firmware and mechanical compatibility with legacy Indramat racks. Thermal management is handled by a built-in internal air blower, allowing enclosure mounting without water lines. Hardware belongs to production 03, an identifier that locks parameters to a fixed hardware layout.

This release is identified as 1, indicating the first fully qualified design spin, and no alternative sub-versions are listed for the catalogue code. Classified as an HDS Drive Controller, it supplies DC-bus energy and field-oriented regulation for individual motor modules while leaving application logic to the PLC. The manufacturer Bosch Rexroth Indramat supports straight retrofits because all I/O, inverter sections, and power connectors match earlier cards in the HDS Drive Controllers series. By unifying communication, cooling, and current capability, the device simplifies spare-part inventory across mixed-age production lines.
