HDS03.1-W075N-HA20-01-FW
The HDS03.1-W075N-HA20-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. As a multifunction axis amplifier, the unit links servo motors to centralized power supplies and higher-level PLCs for closed-loop motion control in packaging lines, material-handling stations, and other automated machinery. It converts control commands into regulated motor current so the connected axis can respond accurately during positioning, speed changes, and load variations. Installed in a coordinated drive rack, it supports multi-axis layouts without requiring a separate standalone enclosure for each motor channel. This arrangement is common in automated equipment that must coordinate several servo functions in limited cabinet space.
The unit communicates motion commands through an analog interface, so velocity or torque references are sent as differential voltage signals that the controller samples in real time. This command method suits systems that use voltage-based motion control rather than networked command channels. Heat generated by switching devices is removed by a built-in air blower, which supports heat sink cooling without external ducting. A continuous output capability of 75 A equips the module for medium-to-high power servo axes supplied from common bus bars. As part of DIAX04, the controller uses the same rack format and connection style found on companion modules.
The controller is part of Line 03 and is built as Version 1. These identifiers distinguish the product generation within the series and keep the hardware description concise. The module is intended for rack-based installation with separate supply components instead of standalone mounting. Its form factor suits centralized drive assemblies where several axes are grouped in one cabinet and controlled from the same automation system. That arrangement keeps motor control hardware organized while leaving the machine axis connected through the rack infrastructure.
