Product Description:

The HDS02.2-W040N-HS91-01-FW is a modular drive controller from Bosch Rexroth Indramat developed for multi-axis systems that rely on digital motion control loops. Belonging to the HDS Drive Controllers series, this unit serves as the power section of an Indramat drive package and regulates current to servo or spindle motors in automated machinery. Within an industrial automation cabinet it pairs with a motion module to translate command words from the control network into precisely modulated motor currents.

The controller exchanges real-time setpoints over the SERCOS fiber-optic interface, so parameter data and drive status share the same deterministic channel as motion commands. Motor power is delivered through a continuous output of 40 A, allowing it to energize medium-frame servomotors without external booster modules. Heat generated by the semiconductors is removed through a built-in internal air blower, eliminating the need for additional cabinet ventilation hardware. The unit is part of the DIAX04 drive family, meaning it can be combined with axis modules and mains supplies that share identical busbars and firmware tools. Hardware identification shows it is from Line 02, so mechanical dimensions and connector layouts match other second-generation HDS devices.

Firmware coding lists the device as Version 2, which determines the range of drive firmware files that may be loaded and sets limits for future functional expansions. The inclusion of the manufacturer name Bosch Rexroth Indramat on the rating plate ensures compatibility with service procedures that apply across the company’s modular drive platform.  Finally, the product type tag HDS Drive Controller clarifies that the module performs current regulation only; motion control intelligence resides in a separate card, and the specified version streamlines firmware selection during maintenance.
