Product Description:

The HDS04.2-W200N-HS38-01-FW is a modular drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within an industrial motion system, it acts as the power and control stage for servo axes, receiving digital commands from higher-level automation equipment and regulating current to connected motors. By integrating into multi-axis racks, the unit supports precise velocity, position, and torque loops for packaging machines, printing lines, and material-handling gantries. It modulates motor current in real time so the axis can accelerate, decelerate, and hold speed as required by the machine cycle. This closed-loop role helps the connected motor respond accurately to changing commands and varying load conditions during operation.

Its command channel is the SERCOS fiber-optic interface, which carries cyclic setpoints and feedback so multiple drives can stay synchronized on a ring. Belonging to the DIAX04 controller family means the hardware uses a common backplane, and power connections, communication boards, and safety modules share standardized slots. The drive can deliver a continuous output of 200 A, a current level suited to large servo motors that need high torque during acceleration. Thermal stability is maintained by a built-in internal air blower, so cabinet air moves across the heat sink instead of relying on external ducting. The blower-based cooling method supports heat removal inside enclosed drive cabinets where several modules operate side by side. Version 2 includes revised gate drivers and monitoring circuits that add extra diagnostic channels.

As part of line 04, the controller mates with matching HVE power supplies, preserving bus bar spacing and DC-link voltages across the rack. The designation HDS Drive Controller identifies the axis module responsible for current regulation, while companion HMS units handle spindle regulation. The product remains within the HDS Drive Controllers series, so it uses the standardized module format shared across the platform. Axis modules and spindle modules are separated by function, which helps the system assign servo control and spindle control to the correct hardware. The rack arrangement keeps the controller aligned with the shared power section and system bus used by adjacent modules.
