HDS03.1-W075N-HS02-02-FW
The HDS03.1-W075N-HS02-02-FW is a drive controller module built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed for cabinet mounting, the unit routes DC bus energy to a servo motor axis under closed-loop feedback and regulates current for controlled motion. In industrial automation, it manages acceleration, deceleration, and steady-state speed so that machine tools, printing lines, and handling robots can follow programmed paths with consistent response. Its role is to act as the power and control stage between the higher-level motion system and the connected motor. The controller suits applications that require repeatable axis behavior during continuous machine operation.
The controller supplies up to 75 A of continuous output current, allowing it to energize medium-power servo axes during sustained operation. Data traffic is handled through a fiber-optic SERCOS ring, which carries cyclic position, velocity, and diagnostic information and removes the need for separate analog command wiring. Thermal management relies on a built-in air blower that moves cabinet air across the heat sink, so external ducting or liquid cooling is not required. As part of the DIAX04 platform, the unit shares the common backplane and bus structure used by related modules. The product is part of Line 03 in the series.
The controller is released as Version 1. It is classified as an HDS Drive Controller, which places it within the standard HDS architecture for axis control. The optical link serves as the command interface, so motion commands, feedback values, and fault messages remain synchronized on the same communication path. This keeps control and status data together during operation and supports coordinated response from the connected axis within a multi-axis cabinet. It also avoids the need for separate signal channels for routine command and feedback exchange.
