HDS02.1-W040N-HS08-01-FW
The HDS02.1-W040N-HS08-01-FW belongs to the HDS Drive Controllers series produced by Bosch Rexroth Indramat. Within an automation cell, this unit acts as the regulated power stage that links a DIAX axis module to a coordinated motion system, converting incoming DC-link energy into controlled three-phase output for servo motors and spindles. By integrating into the series rack, the controller supports multi-axis packaging, metal-cutting, and handling machines where precise velocity and torque loops must operate in sync with the central PLC. Its role in the rack allows multiple axes to respond with consistent timing during demanding motion sequences.
The controller exchanges setpoint, status, and diagnostic data across a SERCOS network, so the optical ring provides deterministic timing for each axis in the drive system. This real-time traffic runs through the unit’s command communication interface, supporting coordinated data exchange without requiring a separate analog command path. A continuous output of 40 A allows the module to energize medium-frame Indramat servomotors without current derating under nominal line voltage. Thermal stability is maintained by a built-in air blower, and the integrated fan draws cabinet air across the heat sink so no external ducts are required. This cooling method helps the controller maintain stable operation when the drive is working under sustained load.
The controller is part of the DIAX04 family, and its power circuitry is keyed to Line 02 to match compatible supply modules and feedback boards from that generation. The unit is cataloged as Version 1, which identifies the initial hardware revision for this model. Its functional description is HDS Drive Controller, indicating a digital drive module used for coordinated torque and speed regulation in rack-based axis systems. This description also distinguishes it from analog-reference drive formats used in older motion control layouts.
