Product Description:

The HDS03.1-W100N-HS25-01-FW is a modular axis drive controller built by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. It is intended for multi-axis cabinets that regulate servo and spindle motors in automated machining cells, packaging lines, and handling systems. By coordinating torque, speed, and position feedback channels, the unit converts digital motion commands into controlled current for connected motors. This role allows one controller to support both steady running conditions and precise axis response during positioning tasks across repeated machine cycles. Because it serves as the central power stage for an axis, the controller handles the electrical conversion needed for commanded motion while the higher-level control manages the motion profile.

The communication backbone of the controller is the SERCOS fiber-optic interface, which streams real-time setpoints and diagnostic data between the drive and the motion CPU with deterministic update timing. Inside the DIAX04 rack, the controller is identified as a single-axis module in Line 03, which keeps its placement clear within that platform. Thermal management is handled by a built-in air blower that pulls cabinet air across the heat sink instead of relying on external cooling ducts. The power section can deliver up to 100 A of continuous motor current, giving the unit the current capacity needed for high-torque acceleration and regulated speed control across coordinated machine sections.

Configuration data stored in the unit identifies it as Version 1. The controller uses the standard backplane bus layout found across the HDS Drive Controllers series, which allows orderly installation beside additional axes in the same cabinet. That shared format keeps field power and signal connections aligned along the rack, and it supports clean integration with other modules in the system. The overall arrangement is intended for compact multi-axis assemblies where several coordinated drives operate from a common cabinet structure in industrial systems. This cabinet-based format also keeps the module accessible without changing the basic system layout.
