Product Description:
The HDS04.1-W200N-HT12-01-FW drive module is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It serves as a high-current servo axis controller inside automation racks, where it closes torque and velocity loops for connected motors. By converting incoming DC bus energy into modulated phase current, the unit supports precise motion in machine tools, packaging equipment, and handling gantries. It is suited to installations where several axes are grouped in one cabinet and coordinated by a central control system. A slot for dedicated cards allows the platform to be adapted for different machine functions.
The command channel uses the SERCOS interface and communicates over fiber optics for synchronized cyclic data exchange between the drive and the master control. This link supports coordinated motion updates without the electrical noise concerns associated with copper communication lines. A continuous output of 200 A allows the module to supply large-torque motors without external boosters. Thermal management is handled by a built-in air blower that moves cabinet air across the heat sink to keep semiconductor temperature within limits during prolonged load cycles. The axis module is part of the DIAX04 family and is assigned to line 04, so it matches the mechanical layout and bus connector positions used by related modules.
The hardware is released as Version 1, identifying the initial design revision of this module. Axis control logic is implemented inside the unit, so no external motion card is required for basic axis operation. The module is intended for coordinated motion systems that use a shared DC bus and centralized rack infrastructure for multiple servo axes. This arrangement keeps power conversion and axis control together in one rack-mounted unit while higher-level machine sequencing remains with the master controller.
