HDS03.1-W100N-HA11-01-FW
The HDS03.1-W100N-HA11-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. In an automation system, it acts as the closed-loop power stage between a motion controller and the motor, converting low-level command signals into regulated high-current output for accurate axis motion. This role lets the unit manage torque and speed response for servo applications while fitting into multi-axis cabinet arrangements that use the same platform. Because it regulates motor current in a closed loop, the controller can respond to changing load conditions during positioning, indexing, and coordinated motion.
This controller receives setpoints through an analog command interface, so speed or torque references are transmitted as proportional voltage signals. This arrangement suits systems that use conventional analog motion commands instead of a digital command network at the drive input. It is built on the DIAX04 architecture, which gives the unit a compatible module layout within that control family. Thermal management uses a built-in air blower that moves cabinet air across the heat sink, and the unit is part of Line 03. The power stage is rated for a continuous motor current of 100 A, allowing it to operate large servo motors that require high current during acceleration and braking.
The controller works with shared system power supplies and SERCOS loop modules, so additional axes can be added within the same drive system without a separate mains input for each axis. It is classified as Version 1, indicating the first release of this controller variant. In cabinet-based drive assemblies, this arrangement supports a modular layout in which supply, control, and axis functions are separated into dedicated components. Its parameter and diagnostic structure follows the same general format used by related modules, which keeps operation consistent in larger multi-axis installations.
