Product Description:

The HDS04.2-W200N-HS32-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. As part of a modular rack, it accepts low-level motion commands from a master control system and modulates its power stage so attached servo or spindle motors receive the current and voltage needed for closed-loop speed, torque, and position control. In automated transfer lines, presses, and CNC machines, the unit forms the interface between numerical motion programs and the mechanical loads they move. That control role lets the drive respond to changing loads while keeping commanded motion profiles stable during production.

At the communication layer, the controller exchanges process data over SERCOS, a real-time fiber-optic ring that maintains fixed telegram timing and synchronized sampling across multiple axes. The electrical design follows the DIAX04 platform, so related units can use the same parameter structure and compatible plug-in cards. The power section is rated for a continuous output of 200 A, allowing it to operate large torque motors without separate booster modules. Internal heat is removed by a built-in air blower, which circulates cooling air along the heat sink fins to help control semiconductor temperature. This communication method also supports coordinated axis behavior when several drives operate on the same machine.

The unit is classified as Line 04, and its housing height matches 300 mm sub-racks used in the same cabinet structure. The front panel and terminal layout remain consistent for this drive type, which helps keep module placement straightforward in a modular assembly. Multiple drives can share a common DC bus, allowing regenerated energy from one axis to be used by another axis in the same enclosure. The shared energy path also reduces wasted braking energy when one axis decelerates while another is accelerating.
