HDS03.1-W075N-HT01-01-FW
The HDS03.1-W075N-HT01-01-FW is a drive controller produced by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. As a drive-level component, it regulates power to servo and main spindle axes, allowing coordinated motion and spindle speed control in automated machinery and production cells. Its task is to accept motion commands from a higher-level CNC or PLC, convert them into controlled three-phase output, and monitor motor current, speed, and torque in real time. That control role allows the unit to support both dynamic axis movement and stable spindle operation in the same machine environment.
This model uses the SERCOS fiber-optic interface, giving deterministic command and feedback exchange between the drive and the machine controller. The controller has a rated output of 75 A, which is the continuous current it can deliver to connected motors, so the selected axis load must remain within that limit. Thermal stability relies on a built-in air blower, which moves air through the housing to remove heat from the power electronics without external ducting. The unit is part of the DIAX04 platform, so it shares mechanical dimensions with other modules in that system. It can be paired in a multi-axis arrangement with HDC or HVE supply units without extra interface modules.
The product is part of Line 03, which indicates the third internal design cycle. It is also Version 1, identifying the revision used for this controller. These identifiers distinguish the controller within the product range without changing its primary role as a closed-loop drive component. The unit is intended for modular drive racks where consistent form factor, regulated motor output, and continuous operating feedback are required. Its operating behavior centers on controlled power delivery and ongoing supervision of motor conditions during machine operation.
