HDS03.1-W100N-HA32-01-FW
The HDS03.1-W100N-HA32-01-FW is a single-axis module in the HDS Drive Controllers series manufactured by Bosch Rexroth Indramat. As a drive controller, it sits between the incoming power supply and the servo motor, shaping current and voltage so that position, velocity, and torque commands from the higher-level motion system are followed accurately. It regulates power delivery during startup, constant-speed operation, and rapid load changes. In an industrial automation rack, the unit controls dynamic motor loads in packaging axes, material-handling gantries, and machining spindles. This layout suits motion systems that require repeatable response during indexing, speed changes, and deceleration.
The command interface accepts an ANALOG reference, so the controller reads a ±10 V or similar signal as the real-time setpoint for speed or torque. This allows continuously variable commands from external motion electronics without a digital network at the drive interface. Thermal management is handled by a built-in air blower, which circulates cabinet air across the heat sink without external ducting. The power section is rated for 100 A of continuous output current, allowing sustained operation with medium to large servo motors. As part of the DIAX04 family, the unit shares backplane connectors and diagnostic protocols with other modules in that platform. The designation 03 marks the performance line used with matching HMS supply units for DC-bus and regeneration management.
Stored drive data is kept on a plug-in memory card, and the unit is Version 1 hardware. Proprietary current-loop control helps reduce following error during fast indexing moves and other rapid changes in demand. The controller also supports four-quadrant operation, so energy can be motored or regenerated through the shared DC link. This allows the drive to handle controlled acceleration and braking through the same power stage.
