HDS03.1-W075N-HS91-01-FW
The HDS03.1-W075N-HS91-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It serves as the power stage in multi-axis automation systems, converting energy from a shared DC bus into regulated motor current for accurate motion control. This allows servo and spindle motors to perform positioning, speed control, and torque control in equipment such as packaging lines, handling systems, and machine tools. In normal operation, the controller closes current and velocity loops so commanded motion profiles are followed with consistent response. The housing and control structure are intended for cabinet-based drive assemblies that require coordinated axis operation.
The controller is part of the DIAX04 family and is assigned to Line 03 in that platform. Command and feedback data are exchanged through SERCOS, a fiber-optic interface that carries real-time setpoints and status information. The power section can supply a continuous output current of 75 A, making the unit suitable for larger synchronous or asynchronous motors. Heat generated during operation is removed by a built-in air blower, so cooling air is directed across the internal heat sink without requiring a separate external fan assembly. This cooling method supports stable operation when the controller is installed with other drive modules in the same cabinet.
Inside the drive system, the module converts DC bus power into controlled three-phase output for the connected motor. The unit is built as Version 1, which identifies the product generation used for this controller. Its design supports shared-bus installations in which multiple axes operate from one supply section while each motor channel remains independently regulated. This arrangement helps keep motion response stable when the machine performs coordinated acceleration, speed changes, and load corrections across several axes. The module is intended for direct integration into a matched drive system rather than for standalone motor control.
