Product Description:

The HDS03.2-W075N-HA14-01-FW is a drive controller manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series. Within a DIAX04 multi-axis system, it converts reference commands into synchronized torque and speed profiles that keep servo motors on track during automated assembly, packaging, or material-handling cycles. The controller acts as the interface between machine-level motion commands and the electrical output required by the motor. Its role is to manage one axis while sharing power supply and system services with neighboring modules, giving the machine a compact control stack for coordinated motion. By using a shared rack structure, the module supports coordinated motion without requiring a separate standalone controller for each axis.

The controller exchanges setpoints through the ANALOG command interface, so voltage or current loops from the supervisory PLC can directly modulate shaft velocity without digital bus overhead. That arrangement suits systems that already use analog reference signals for axis control. A continuous output of 75 A allows the unit to supply the current needed for rapid acceleration and sustained torque on larger servo axes. Thermal energy is removed by a built-in internal air blower, which circulates cabinet air across the heat sink instead of requiring external ducting. Because the cooling air remains inside the cabinet, enclosure airflow still has to carry heat away from the module area. The unit is part of Line 03, so it follows the wiring and terminal arrangement used for that design line.

The controller is Version 2, indicating a later revision within this model line. Functionally, it is an HDS Drive Controller with absorber circuits, current regulators, and safety interlocks rather than motor-mounted power electronics. The control section manages drive behavior at the module level while the connected motor provides the mechanical output on the axis. This rack-mounted arrangement keeps the power and regulation functions together in the drive assembly and supports coordinated operation with neighboring modules. The absorber circuits help handle returned energy inside the system, while the current regulators support stable motor response during changes in load.
