HDS04.1-W200N-HA12-01-FW
The HDS04.1-W200N-HA12-01-FW is a modular drive controller produced by Bosch Rexroth Indramat. It is positioned within the HDS Drive Controllers series and regulates current and velocity loops for servo and main spindle drives in multi-axis equipment. By receiving analog command signals from higher-level control hardware and converting them into precise motor current, the unit links programmed instructions to real machine movement. Because the electrical control loops are closed inside the module, the connected motor can respond quickly to speed and torque changes. This role is useful in machine tools and automation systems that require synchronized axis behavior throughout repeated operating cycles.
Its command channel is the analog interface, so velocity or torque references are transferred as ±10 V signals rather than by fieldbus frames. The controller belongs to the DIAX04 family, and thermal management is handled by a built-in air blower that pulls cabinet air through the heat sink fins. Current capability reaches 200 A, permitting direct connection to high-torque spindle or large servo motors without an intermediate amplifier stage. The unit occupies the rack position identified as Line 04, which sets its connector arrangement and mounting width within the drive stack. This layout supports organized placement in cabinets where several drives operate together on a shared motion system.
This hardware is classified as an HDS Drive Controller. The unit is released in Version 1. Diagnostic LEDs and standardized parameter numbering remain consistent with other motion modules installed in the same rack, which keeps status interpretation straightforward during operation. The controller is intended for coordinated drive assemblies where several axes share a common platform and require predictable response from the power stage. Its modular format also fits stacked cabinet layouts where neighboring drives are arranged side by side for centralized motion control.
