HDS03.1-W100N-HS38-01-FW
The HDS03.1-W100N-HS38-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Designed for mounting in multi-axis racks, the unit conditions power and delivers closed-loop control signals to servo systems used on machining centers, printing lines, and other automated equipment. It acts as the link between higher-level PLC commands and individual motor axes, so commanded torque, speed, and position can be regulated with consistent timing. By coordinating motion across several axes, it supports synchronized starts, stops, and speed changes in equipment that cannot tolerate timing drift. This operating role suits production systems that rely on repeatable motion from a centralized drive cabinet.
The controller exchanges cyclic data through the SERCOS fiber-optic ring, allowing real-time setpoints to reach the drive with deterministic timing. That communication path also carries status information needed for closed-loop response during operation. A continuous output of 100 A allows the device to supply large servo axes without external current boosters. Thermal management is handled by a built-in air blower, which moves cabinet air across the heat sink and removes the need for water cooling or external fans. The unit is built for the DIAX04 platform and is assigned to Line 03, so its mechanical layout and connector arrangement match related modules in the same rack.
Configuration details identify the unit as Version 1. It is classified as an HDS Drive Controller, which distinguishes it from smaller inverter products and places it in a rack-based servo control system. In use, the controller manages the current and command interface needed for coordinated axis motion while supporting the fast response expected in closed-loop automation. The rack-mounted format helps keep power conversion and motion control functions organized within a centralized assembly. This layout is appropriate for machines that group several servo axes in one control section.
