Product Description:

The HDS03.2-W075N-HA22-01-FW is a modular axis drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It operates as the power stage for DIAX04 motion systems, supplying closed-loop regulation to servo motors and spindle modules on multi-axis machines. By converting incoming DC bus energy into controlled three-phase outputs, the unit supports the speed, torque, and position functions used in packaging lines and machining centers. This arrangement lets a higher-level controller issue motion commands while the drive manages the regulated motor output. It is suited to coordinated equipment where several axes share the same motion platform.

The drive has a continuous rated output current of 75 A, allowing it to supply medium-power servo axes without derating under normal operating conditions. All command signals enter through the ANALOG interface, so velocity or torque references can be delivered as ±10 V signals from the motion card. Thermal management is handled by a built-in air blower, which draws cabinet air through the heat sink to keep internal components within their permitted temperature range. As part of the DIAX04 family, the unit shares the mechanical format used by related modules in the same system. The product is part of Line 03, which identifies this design line within the series.

The drive is Version 2. It is an HDS Drive Controller that uses onboard processing to handle control and diagnostic functions during operation. A plug-in control card supports the electronic control section without changing the external pin layout. This modular layout separates the control electronics from the main power section and keeps the unit consistent with rack-based drive assemblies. That arrangement suits cabinets that already use shared system power and centralized motion hardware. The module is intended for drive racks that provide the required DC link and enough cabinet airflow for stable operation.
