Product Description:

The HDS03.1-W100N-HT10-01-FW is a drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. In a multi-axis DIAX platform, the unit converts DC-bus energy into controlled motor current and interprets motion commands for coordinated servo operation. It serves as the power and regulation stage for servo axes that must track commanded speed and torque values during continuous machine cycles. That role makes it suitable for precise starts, stops, and speed changes on coordinated machine axes in automated equipment.

Motion instructions reach the controller through the SERCOS fiber-optic interface, so deterministic cycle timing is maintained between the drive and a central CNC or PLC. This communication method supports synchronized command execution and consistent cyclic data exchange. This model belongs to the DIAX04 platform, so it uses the same feedback processing approach across compatible axes. Thermal loads from the switching devices are removed by a built-in air blower, so cabinet air is drawn through the heat sink without requiring an external cooling plate. The controller can deliver up to 100 A, allowing it to operate high-torque servo motors in demanding axis applications. The product is part of Line 03, and its connector placement and overall layout match other units in the same design line.

The drive is Version 1, so its parameter set and diagnostic behavior correspond to the initial release of this model. It functions as an HDS Drive Controller, which means the power stage, control logic, and communication functions are housed in one unit. This arrangement keeps the main drive functions together instead of dividing them across separate modules. The controller is intended for use with DIAX04 power supplies, motor feedback options, and SERCOS-based master stations already installed in existing automation systems.
