HDS03.1-W075N-HA22-01-FW
The HDS03.1-W075N-HA22-01-FW is a drive controller module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a DIAX rack, the unit works with supply and feedback cards to energize one servo axis and translate external references into closed-loop motor regulation. This role helps automated machining cells, pick-and-place assemblies, and material-handling stations maintain commanded position, velocity, and torque profiles without requiring an external motion processor. Because the controller is installed as a rack module, it can be combined with matching system components in compact multi-axis cabinets.
The controller accepts command signals through an ANALOG interface, so velocity or torque references arrive as ±10 V levels from a PLC or motion card without digital fieldbus overhead. It belongs to the DIAX04 controller family, so its diagnostics and parameter structure match other axes in that platform for coordinated motion. The power stage is rated for 75 A of continuous output, allowing the unit to drive medium-to-large synchronous or induction motors while keeping current ripple within servo tolerances. Thermal management relies on a built-in air blower that draws cabinet air across the heatsink, and the designation Line 03 places the module in the third mechanical design generation. This arrangement supports stable operation during sustained axis loading in enclosed control cabinets.
The drive controller is Version 1. It is an HDS Drive Controller that uses a modular power-supply architecture, so the rack uses separate supply modules rather than an integrated power stage for every axis. Its self-contained cooling arrangement limits the temperature rise seen by neighboring drives, and enclosure airflow can be based on the ambient load instead of added ducting for each axis. That layout also leaves power distribution and feedback handling organized at the rack level instead of inside the motor connection area.
