Product Description:

The HDS03.2-W075N-HT22-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. As an axis amplifier in the DIAX04 platform, it regulates current and velocity loops for AC servo motors used on production lines, packaging cells, and material-handling stations. The unit converts commands from higher-level motion control into controlled motor power for coordinated multi-axis movement. In this role, it serves as the power stage between the motion controller and the motor. This allows servo axes to accelerate, decelerate, and hold speed with the repeatability needed for automated handling and synchronized machine cycles. It is suited for systems where stable closed-loop control is required across multiple connected axes.

Real-time communication is handled over the SERCOS interface, allowing deterministic cycle timing for synchronized motion and fast status exchange. A continuous output capability of 75 A lets the power section drive high-torque motors during sustained acceleration and steady running. Thermal stability is supported by a built-in air blower, which moves cabinet air across the heat sink so no external liquid loop is required. This cooling method supports compact cabinet integration when vertical airflow paths are available. Setpoint commands and operating status move across the same fiber-optic channel, which helps maintain coordinated axis timing. The module is Version 2, which places it in the later revision of this controller type.

The product is part of Line 03, so it follows the mechanical and electrical layout used for that design line. As an HDS Drive Controller, the module fits directly into distributed servo cabinets and works with compatible power supplies, auxiliary cards, and bus rails. Shared mounting dimensions and cabling arrangements help keep panel layout orderly in multi-axis systems. The enclosure format also supports consistent placement beside neighboring drive modules. The controller can be grouped with other modules in the same platform without special adapters or custom spacing parts. This makes it practical for machine sections that need centralized cabinet installation with coordinated axis control.
