Product Description:
The HDS03.1-W100N-HA42-01-FW is a modular drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed for multi-axis automation racks, it converts velocity and position commands from the machine control layer into regulated motor currents, enabling precise coordination of conveyor sections, pick-and-place robots, and press feeds. By housing power electronics, control logic, and diagnostic circuitry in one enclosure, the unit simplifies cabinet layout and allows axes to share a high-voltage DC bus supplied by a separate power module. Integrated monitoring routines detect short circuits, over-temperature, and encoder faults to protect both the motor and the production process.
The controller receives setpoints through an ANALOG command interface, so velocity or torque references arrive as ±10 V signals generated by legacy motion cards or PLCs. Its power stage is rated for 100 A, allowing continuous delivery of that current to the motor windings without derating under standard ambient conditions. Thermal energy is removed by a Built-in Internal Air Blower that draws cabinet air across the heat sink, eliminating external ductwork. Membership in the DIAX04 controller family grants identical bus connectors and parameter addressing to companion axes, facilitating rapid replacement and uniform commissioning routines.
Hardware coding designates the module as line 03, placing it within the third-generation boards that incorporate revised bus couplers. Firmware identification sits at version 1, so parameter files must match this release to avoid incompatibility alarms. The product label HDS Drive Controller confirms adherence to the wiring and feedback schemes standardized for the rack. Alternative variants are not listed; the specification records None under other versions, which simplifies spare-part logistics. During start-up, the autotune wizard adjusts the drive’s current loop, letting technicians match motor inductance without opening the enclosure.
