HDS03.2-W100N-HA15-01-FW
The HDS03.2-W100N-HA15-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation rack, this unit regulates power modules and servo motors, executing velocity and torque commands that originate from higher-level motion systems. It integrates with rack-based drive assemblies to provide coordinated multi-axis control, and it translates reference signals into regulated three-phase outputs for the attached motors. In typical servo systems, it serves as the control and power interface between the rack supply and the motor. This allows the axis to respond smoothly to changing load conditions during automated motion.
The command section accepts an analog reference, so motion setpoints are delivered as voltage or current levels rather than through a digital network. This makes the unit suitable for systems that use external command cards or conventional control electronics instead of networked motion buses. Thermal management uses a built-in air blower that forces air across the heat-sink fins to keep internal components within their operating range during continuous duty. The power stage carries a rated output of 100 A, allowing the controller to sustain substantial motor current when cabinet airflow is maintained. The unit is part of Line 03, and it is listed as Version 2 for this configuration.
The unit belongs to the DIAX04 platform, which supports plug-in backplane communication and common auxiliary supplies with companion modules. As an HDS Drive Controller, it slots beside power supplies and auxiliary axes in modular motion systems. This arrangement supports a shared regenerative bus for coordinated axis operation, and it keeps the drive assembly compact inside the control cabinet. Common auxiliary supplies reduce the need for separate support modules on each axis and keep the rack layout consistent. Centralized module placement also simplifies routing between the controller, power section, and connected motors.
