Product Description:

The HDS03.2-W075N-HT82-01-FW is a drive controller from Bosch Rexroth Indramat's HDS Drive Controllers series. Within an automation cell, it serves as the closed-loop interface between a supply unit and a synchronous or induction motor, supervising current, speed, and position according to incoming motion commands. The unit combines power electronics, command processing, and cooling in one housing, which helps keep cabinet layouts compact in multi-axis systems. This arrangement suits machining centers, pick-and-place lines, and material-handling gantries where coordinated motion and stable axis control are required throughout repeated production cycles. Because the control and power sections are housed together, the unit reduces the need for separate interface modules between the supply stage and the motor axis.

The controller exchanges process data through a SERCOS optical ring, so connected axes can share synchronized setpoints and diagnostic telegrams with very low timing variation. This communication path supports coordinated command execution and consistent status reporting across the ring. It belongs to the DIAX04 family and uses a mounting footprint that matches related motion modules in the same platform. Heat generated by the IGBTs is removed by a built-in air blower, which eliminates the need for external ducting and supports use in densely packed enclosures. The product is part of Line 03, and the power stage can deliver a continuous motor phase current of 75 A for medium-frame servo applications.

The drive is Version 2. In this revision, functions such as electronic gearbox, master-slave coupling, and enhanced alarm text are available for motion control and status reporting. Its mechanical outline and parameter map follow the rest of the product line, so axis modules can be arranged in a consistent cabinet layout. That layout keeps electrical and control functions closely grouped around each axis, which is useful in compact multi-axis cabinets.
