HDS03.2-W100N-HT70-01-FW
The HDS03.2-W100N-HT70-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for multi-axis automation racks. It occupies one slot on a shared DC bus and converts high-power supply energy into regulated motor current for one assigned axis. This arrangement lets the rack distribute DC power centrally while each controller regulates its own motor current locally. By processing command data from the motion system, the unit coordinates torque, speed, and position in machining centers, printing lines, and material-handling equipment. Its modular format also allows it to operate beside compatible rack components in compact control cabinets.
Its control layer communicates through the SERCOS interface, allowing cyclic setpoint updates and real-time diagnostics over an optical ring. The unit belongs to the DIAX04 family, so it mates mechanically and electrically with compatible power supplies, auxiliary cards, and bus bars in the same rack. Thermal management is handled by a built-in air blower, which pushes cabinet air across the heat sink for continuous operation. The optical link helps reduce susceptibility to electrical noise in cabinets with high switching currents. The controller has a continuous output current of 100 A, which is the allowable RMS phase load delivered to the motor windings during sustained operation while still supporting dynamic response.
The designation Line 03 places the unit in the third design line, so its mounting pattern and busbar spacing match other modules in that line. The drive is Version 2, indicating the second version of this model. It is part of the HDS Drive Controllers series and is intended for high-current axis control in rack-based servo systems. These identifiers help distinguish the controller within the product range without changing its basic slot-based integration into the rack.
