Product Description:

The HDS03.2-W100N-HT76-02-FW is a drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. It is intended to regulate servo motion in multi-axis machining centers, handling coordinated motion and torque delivery for linked machine functions. By translating high-level position commands into phase-synchronized motor currents, the unit supports tightly controlled industrial automation tasks such as packaging, printing, and material removal. This operating role allows the controller to manage acceleration, speed changes, and holding behavior so connected axes can follow commanded motion with stable response during repetitive production cycles. It is suited to applications where repeatable motion and consistent torque control are required across more than one axis.

The controller exchanges set points and feedback through the SERCOS fiber-optic interface, allowing deterministic communication with the machine PLC. Its logic and power sections are part of the DIAX04 family, so it mates mechanically and electrically with companion supplies and I/O modules in that platform. A built-in air blower moves cooling air across heat-dissipating components, which helps maintain stable operation during continuous use. This arrangement removes the need for separate cabinet fans and keeps airflow concentrated around the controller. The power stage is rated for 100 A continuous output, giving the unit headroom to drive medium-to-large synchronous or asynchronous motors without current derating. It can therefore support demanding load changes while maintaining controlled current delivery to the motor.

The unit is part of Line 03, which places it in the third design line of this controller platform. It is Version 2, identifying the product generation used for this model. These codes are used with the module designation to distinguish this controller within populated drive racks. In systems with several installed modules, this identification helps separate one controller type from another without relying on external descriptions.
