Product Description:

The HDS03.2-W075N-HS12-01-FW belongs to the HDS Drive Controllers series from Bosch Rexroth Indramat. As a digital drive controller, it coordinates power delivery and motion commands between a supply module and multiple servo axes, enabling synchronized positioning in automated handling equipment, machine tools, and packaging lines. Installed in a modular rack slot, the device converts fieldbus commands into controlled current and voltage for connected motors. This allows the drive system to respond to changing load demands while maintaining coordinated motion across linked axes.

Communication with the central control system is established through the SERCOS optical interface, which carries real-time setpoints and feedback with deterministic timing for multi-axis interpolation. This real-time optical link supports synchronous command exchange and stable feedback transfer during coordinated motion. Within the broader DIAX04 family, the module shares the same rack format and interface structure as related units. Thermal dissipation relies on a built-in air blower, so cabinet air moves through the heat sink without external ducting. The power section delivers a continuous output of 75 A, supporting medium-to-high torque motors during sustained motion profiles. The unit is part of Line 03.

The hardware is issued as Version 2, which includes updated gate-driver and diagnostic circuitry while keeping operation aligned with earlier machine programs. The unit is an HDS Drive Controller, so it regulates motor current as well as velocity and position loops rather than serving as a power supply. Its control functions are intended for coordinated axis operation in rack-based drive systems. Diagnostic functions are handled inside the controller, helping the drive report operating status during motion and fault monitoring.
