HDS03.1-W100N-HA38-01-FW Bosch Rexroth Indramat

Product Description:

The HDS03.1-W100N-HA38-01-FW is a drive controller from Bosch Rexroth Indramat, belonging to the HDS Drive Controllers series. As an axis amplifier inside the DIAX modular drive system, it regulates power flow between a DIAX supply module and a servo motor. Designed for multi-axis automation, the unit converts incoming DC bus energy into controlled three-phase output required for dynamic positioning tasks. By managing current and velocity loops in real time, the drive contributes to accurate motion profiles in machine tools, handling systems, and printing lines.

Signal exchange with the supervisory PLC occurs through a ANALOG command interface, so speed or torque references are transmitted as continuous voltage values rather than fieldbus telegrams. The controller is engineered for a continuous motor phase output of 100 A, giving it capacity to drive large and rapidly accelerating axes. Internally, a Built-in Internal Air Blower moves cooling air across heat-sinks, which removes losses without external ducting and keeps semiconductor junction temperatures under permissible limits. This HDS device is part of the DIAX04 automation family, meaning it shares back-plane connections, diagnostic semantics, and mechanical dimensions with other members of that platform. Functionally it is classified as an HDS Drive Controller, indicating that it works in conjunction with a separate supply module rather than rectifying mains power itself.

The model code shows it belongs to line 03, a design iteration that introduced higher current tracks and refined gate drivers, while the build 1 identifies the initial hardware version for this line. Integration is straightforward because parameter files and mounting patterns match every unit in the HDS Drive Controllers series, allowing a technician to swap modules without cabinet modifications or software restructuring.
