Product Description:

The HDS04.2-W200N-HS37-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It works as the power and control stage in automation racks, processing motion commands from a master control system and regulating current to the motor phases. By converting DC bus energy into controlled output for connected axes, it supports torque and speed regulation during synchronized machine movement. In factory cells, the module links the central PLC with servo motors so equipment can index, cut, and convey material with repeatable position control.

Communication is handled through the SERCOS fiber-optic bus, which carries cyclic setpoints and feedback signals at high speed without separate analog wiring. That digital link lets the controller receive commands and return axis status within the same network cycle. As part of the DIAX04 family, the controller uses the same rack format and operating structure as related modules. Thermal management is provided by a built-in air blower, which draws cabinet air through the heat sink. The power section is rated for 200 A of continuous output current, giving the unit the current capacity needed for large servo motors and demanding acceleration profiles. The drive also includes integrated braking choppers and DC link monitoring to support stable inverter operation during dynamic motion and deceleration.

The unit is part of Line 04, which places it in the fourth design line of this controller platform. It is built in Version 2. An optimized airflow path inside the housing helps keep the power semiconductors within their operating temperature range during continuous duty in densely packed enclosures. This internal air route supports even cooling across the main heat-generating components and reduces localized heat buildup near the power stage.
