Product Description:

The HDS03.2-W100N-HA29-01-FW is a drive controller built by Bosch Rexroth Indramat. As a modular axis module in multi-axis drive systems, the unit provides closed-loop power conversion so servo or main spindle motors can be accelerated, decelerated, and held at commanded setpoints from upper-level motion logic. It is installed in industrial automation cabinets where it bridges supply power to motor windings while exchanging status data with supervisory control electronics. This arrangement lets the controller serve as the power stage between the cabinet supply infrastructure and the connected motor axis.

The controller delivers a continuous output of 100 A, which is the current it can sustain during operation without thermal derating. Command signals reach the power stage through the analog interface, allowing ±10 V velocity or torque references from a PLC or motion card. The analog input makes the unit suitable for control platforms that send conventional reference signals instead of digital command data. Temperature rise is limited by a built-in air blower that moves cabinet air across the heat sink, so no external ducting is required. Compatibility with the DIAX04 family keeps power connections and feedback channels aligned with standardized backplane and inter-bus layouts. The unit is part of Line 03 in the series.

The controller is built as Version 2, which identifies its build level within this product line. It is classified as an HDS Drive Controller, so it supports current, velocity, and position loops rather than frequency conversion alone. It is also part of the HDS Drive Controllers series, which uses consistent mounting rails, bus bars, and diagnostic connections across adjacent axes. The modular layout allows the unit to sit beside companion axes in the same cabinet without changing the basic mechanical arrangement or connection scheme.
