HDS03.2-W075N-HA44-01-FW
The HDS03.2-W075N-HA44-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat and supplied in the HDS Drive Controllers series. Installed in multi-axis racks, the unit converts command references from a machine controller into controlled output for servo power modules that drive motors in automated machinery. Its role is to close the motion feedback loop, deliver power, and perform protective monitoring so that each axis maintains commanded speed, position, and torque during operation. This arrangement lets the controller regulate axis behavior while responding to machine commands and shutdown conditions in real time.
The controller receives setpoint signals through an analog interface, meaning it interprets voltage references rather than serial fieldbus frames. Because it belongs to the DIAX04 family, its back-plane connectors align with the supply and communication rails used in that platform. A continuous output capability of 75 A allows the device to energize medium-to-high torque servomotors without an external booster stage. Thermal energy from that current is expelled by a built-in air blower, which draws cabinet air through the heat sink and keeps component temperatures within the approved range. Functionally, it is an HDS Drive Controller, so the control electronics and power section share the same housing. This interface and cooling arrangement supports stable control in systems that still use direct voltage references from external motion hardware.
The designation Line 03 identifies the power section revision for this unit. The product is marked as Version 2, so it follows the second release used for this model line. It mounts on standard guide rails, which helps keep cabinet layouts uniform across a drive rack. The guide-rail format also supports orderly module placement when several axes are installed side by side, and it keeps the controller aligned with adjacent rack components during installation.
