Product Description:

The HDS02.1-W040N-HA32-01-FW is a modular axis drive controller from Bosch Rexroth Indramat, supplied within the HDS Drive Controllers series. In a DIAX04 multi-axis rack it acts as the power and regulation stage for a single servo or spindle, converting reference commands into precise motor currents and speeds. This role lets the unit maintain closed-loop accuracy for packaging, printing, and material-handling equipment that require reliable motion control.

Command data enters through an ANALOG interface, so the regulating electronics accept ±10 V or 0–20 mA references from a PLC or motion card. The power section is rated for 40 A continuous output, enabling medium-frame synchronous or induction motors to run without derating. Hardware identification lists line 02, and the hardware release shown as Version 1 defines component layout and firmware pairing for this build. Membership in the DIAX04 controller family keeps bus wiring, parameter structures, and diagnostics uniform across the cabinet. Heat generated by the IGBT bridge is removed by an integrated internal air blower that channels cooling air along the heatsink, eliminating the need for separate ducting.

Within a multi-axis cabinet the Bosch Rexroth Indramat service tools recognize the unit automatically, shortening commissioning time. Because it belongs to the HDS Drive Controllers architecture, firmware and parameter files are interchangeable across axis sizes, simplifying spare-parts logistics. The modular DC link shares regenerated energy between axes, and the intelligent drive controller modulates blower speed according to internal temperature sensors, keeping component stress low during load peaks referenced earlier. The analogue command path also obliges system designers to use shielded cabling and proper grounding to prevent noise from degrading position accuracy.
