HDS03.2-W100N-HA32-01-FW
The HDS03.2-W100N-HA32-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It links a machine's motion-control layer to the power stage that drives servo and spindle motors. In industrial automation, the unit regulates motor speed, torque, and direction so numerically controlled tools, packaging lines, and material-handling axes can follow precise motion profiles. The controller converts command signals into regulated motor behavior for positioning tasks, spindle control, and synchronized axis movement across automated equipment. Its modular format allows it to fit into multi-axis drive racks, and it supports motion systems that need repeatable response without relying on mechanical relays for switching.
This model provides a continuous output current of 100 A, allowing it to operate large-frame motors that require high torque during acceleration and sustained load changes. Command signals are accepted through an analog interface, and a ±10 V reference from the higher-level controller is translated directly into current commands. This input method suits systems that use voltage-based motion references and helps simplify integration with older CNC and PLC platforms. Thermal management is handled by a built-in air blower that moves ambient air through the heat sink and exhausts it upward. The airflow path helps keep semiconductor temperatures within a safe operating range without external ducting.
The controller is part of the DIAX04 family, so its power section can share a common DC bus with other rack modules during coordinated multi-axis operation. It is assigned to Line 03, and Version 2 marks the second revision of that line. Protection logic monitors blower speed, heat sink temperature, and command signal validity so the unit can shut down quickly if a fault occurs. This arrangement also allows braking energy to return to the supply during deceleration instead of being dissipated entirely by external hardware. This behavior is useful on cyclic axes with frequent acceleration and deceleration.
