Product Description:

The HDS03.1-W100N-HA28-01-FW is a modular drive controller module produced by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. It serves as the power and regulation stage between higher-level motion processors and the motor armature in automated production cells, providing precise current control for rapid speed and torque regulation.

The controller exchanges motion and status data over a ANALOG command interface, so its set-point arrives as low-voltage reference signals from the supervisory hardware. Membership in the DIAX04 control family means the unit fits the same bus bars, DC link, and programming framework as other axes in that multiaxis platform. Thermal management is handled by a built-in internal air blower, allowing the module to expel heat without relying on external cabinet fans. Continuous motor demand is supported by a rated output current of 100 A, giving the unit the capacity to drive large synchronous or induction motors at full torque. Manufacturing quality from Bosch Rexroth Indramat ensures protective functions such as short-circuit detection and I²t monitoring are integrated at the factory.

Hardware designation places this drive in line 03, meaning it shares mounting dimensions and connector layout with other third-generation cards in the family. The internal build is revision 1. The unit is listed by the manufacturer simply as an HDS controller and remains fully compatible with the larger HDS Drive Controllers series, allowing mixed installation alongside regenerative and supply modules from the same rack. Firmware is delivered separately under the –FW suffix, letting plant engineers load motion functions that match their process without changing the base electronics.
