Bosch Rexroth HDS03.2-W075N Servo Drive Module

The Bosch Rexroth Indramat HDS03.2-W075N servo drive module is a high‑performance HDS Drive Controller from the DIAX04 family, designed to drive three‑phase servo motors with SERCOS for command communication. As part of the Indramat DIAX04 line, it supports servo applications with MKD, 2AD, and 1MB AC motors and can interface with spindle drives, making it suitable for precision automation tasks. Key specs include a continuous current per axis around 37 A, a maximum output current of 40 A, and a maximum output frequency of 1000 Hz, with a DC bus input of 530–670 V and a control voltage input of 26 V DC; it dissipates about 220 W under continuous load. The enclosure measures 498 mm in height, 308 mm in depth, and 100 mm in width, weighs 11 kg, and is built for industrial reliability in demanding environments. Model designation R911190231, with firmware variants such as HS12‑01‑FW and HS37‑01‑FW that indicate SERCOS interfacing and DIAX04 compatibility.
