Product Description:

The HDS03.1-W100N-HS23-01-FW is a modular drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within a DIAX04 multi-axis platform, the unit functions as a power section that regulates current for servo or spindle axes when paired with an HVE supply module. In industrial automation, it delivers position, velocity, and torque control for machine tools, printing lines, and handling systems that require fast, coordinated motion. Its role in the system is to convert DC-bus energy into controlled motor current so the connected axis can respond accurately to changing load conditions. That makes it suitable for applications where multiple axes must accelerate, decelerate, and hold position in step with one another.

The drive is specified for a continuous output of 100 A, allowing it to energize large synchronous or induction motors under nominal conditions. Command signals and diagnostic data pass through the SERCOS fiber-optic interface, which provides deterministic communication and electrical isolation from the controller. Thermal stability is maintained by a built-in air blower, so cabinet air is pulled across the heat sink rather than relying on external fans. The designation Line 03 identifies the product line used for this controller. This arrangement supports coordinated multi-axis operation in systems that depend on consistent current regulation and fast signal exchange. Because the cooling air moves through the controller itself, cabinet ventilation still has to remove the heat rejected by the power electronics.

The drive is Version 1. Classified as an HDS Drive Controller, the unit is intended for use as a high-current axis module in rack-based drive assemblies. It is suited to applications that need substantial continuous current while maintaining closed-loop control of motor speed and torque. Its modular layout also allows the controller to operate alongside supply and feedback components in the same system without requiring a separate standalone enclosure. The controller can be integrated into larger motion systems where several drives share common supply architecture and centralized command timing.
