HDS03.1-W100N-HA15-01-FW
The HDS03.1-W100N-HA15-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It is installed in modular automation racks to supply regulated power to servo and spindle motors, executing velocity and torque commands in production lines and machine tools. The unit serves as the power stage between the machine control and the motor, converting energy from the rack supply into controlled motor current. The module fits beside other drive cards and receives its supply from a shared DC bus, allowing compact multi-axis assemblies.
Parameter exchange with the drive occurs through an analog command interface, so velocity loops generated by the CNC or PLC are carried to the controller as ±10 V differential signals. A continuous output capability of 100 A allows the module to energize high-torque motors without external boosters, and electronic current limiting inside the unit helps maintain thermal stability during short overloads. Heat generated by the IGBT bridge is removed by a built-in internal air blower, eliminating the need for cabinet ducting and helping keep power components within acceptable operating temperatures. The controller is part of the DIAX04 architecture, so it can operate with other axes on the same platform. This arrangement supports coordinated motion in machines that group several drive modules in one rack.
The designation Line 03 places the controller in the third mechanical format of the product line, matching backplane height and connector spacing used in medium-power racks. This format lets the module sit beside companion units in the same rack without changing the cabinet layout. The controller is Version 1. Its coding identifies the product generation used for this unit while keeping the description focused on the fixed features of the model.
