HDS03.1-W075N-HA23-01-FW
The HDS03.1-W075N-HA23-01-FW is an axis drive module manufactured by Bosch Rexroth Indramat for use in automated production lines that require accurate motor control. As part of the HDS Drive Controllers series, it receives command signals from higher-level motion processors and modulates motor power so position and velocity follow programmed profiles in packaging, printing, and material-handling machinery. The module is intended for closed-loop speed and torque regulation, making it suitable for servo or spindle axes that must respond consistently to changing loads. This type of controller is commonly installed in coordinated motion systems where multiple axes must operate with repeatable timing and stable response.
This controller exchanges velocity or torque commands through an analog interface, which supports connection to legacy PLC hardware and other systems that use analog setpoint transmission. Its power stage is rated for a continuous output of 75 A, allowing it to energize medium-size servo or spindle motors under normal operating conditions. Internal thermal management is handled by a built-in air blower that moves cabinet air across the heat sink without external ducting. The control structure aligns with the DIAX04 multi-axis platform, which keeps diagnostics and parameter handling consistent across the drive rack. During operation, the module regulates output current in response to feedback and command changes so the axis can maintain steady motion through acceleration and load variation.
The unit is part of Line 03 and is supplied in Version 1 form. In a multi-axis cabinet, it connects to a shared DC bus from the supply module and uses that energy source to drive the motor phases. It accepts resolver or incremental encoder feedback so the control section can compare commanded and actual motion in real time. The current loop is executed inside the module, helping the motor hold the requested torque and speed during continuous duty and rapid changes in demand. That arrangement allows the drive to correct deviations quickly when the axis encounters inertia changes or process resistance.
