HDS03.2-W100N-HS04-02-FW
The HDS03.2-W100N-HS04-02-FW is a modular axis controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. As a rack-mounted power stage for servo and main-spindle motors, it operates in industrial automation cells where coordinated, closed-loop motion is required. The module interprets high-level motion commands, modulates its output, and supplies regulated three-phase current to connected drives. This supports precise speed, torque, and position control across multiple machine axes in synchronous applications. It is suited for machinery that depends on synchronized motion and stable response during continuous industrial use.
Communication with the supervisory CNC or PLC is handled through the SERCOS interface, a real-time fiber-optic bus that carries command data and status feedback on one deterministic channel. Within the DIAX04 family, this unit is identified as Version 2. Cooling is provided by a built-in air blower, so the heat sink can dissipate switching losses during operation without relying only on cabinet airflow. During continuous operation, the power stage can supply up to 100 A of output current, allowing it to drive medium-to-large synchronous or induction motors under nominal ambient conditions. The communication path and cooling method support steady control performance during multi-axis operation.
The module is part of Line 03, which indicates its mechanical dimensions and connector arrangement within the product range. It is categorized as an HDS Drive Controller for use in modular multi-axis systems. The rack format allows the unit to be installed beside companion modules in the same cabinet, keeping control wiring and power connections in a consistent layout. Front-access connections also help maintain orderly integration inside drive racks where several axes operate together.
