Product Description:

The HDS04.1-W200N-HS94-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It functions as an axis module within DIAX04 automation racks, translating motion commands into regulated motor current for coordinated multi-axis movement. By integrating power electronics, logic, and its own blower in one housing, the unit supports precise torque and speed regulation in packaging, printing, and material-handling machinery. Because current control is handled inside the module, linked axes can react quickly during indexing, feeding, and speed-matching tasks without depending on constant corrective action from the higher-level control.

Communication with the host system is handled through the SERCOS fiber-optic interface, which provides deterministic cyclic data and reduces susceptibility to analog noise. Thermal management relies on a built-in air blower, so airflow is generated inside the controller without requiring a separate external cabinet fan. The power stage can supply 200 A of continuous output current, allowing high-torque axes to accelerate heavy loads and sustain demanding duty cycles. The unit is part of DIAX04 and is identified as Line 04. The controller is Version 1, which places it within the first revision level for this model.

The module operates on a common DC bus, so regenerated energy from one axis can be used by another axis in the same rack. The designation HDS Drive Controller indicates that position and velocity loops close within the module, which reduces processing demand on the central PLC and keeps motion response local to the drive. This layout allows the card to sit beside higher- or lower-current modules on the same SERCOS ring without changing the basic communication method. Local loop closure also helps maintain stable motion behavior when several axes accelerate or decelerate at the same time, and the internal airflow supports cooling when adjacent slots are occupied.
