HDS02.1-W040N-HA19-01-FW
The HDS02.1-W040N-HA19-01-FW is a supply and control module designed by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a DIAX04 rack, it distributes regulated DC-bus energy and processes command references so connected HVE power supplies and HMS servo inverters can operate synchronous or asynchronous motors. It serves as the control link between rack-level power distribution and the axis modules that execute motor commands. This arrangement supports coordinated current, speed, and position control in packaging lines, printing presses, and machining centers that require precise multi-axis motion. By handling these tasks in one rack-mounted unit, the controller helps connected axes follow shared motion profiles during acceleration, steady speed, and stopping.
The controller exchanges velocity or torque references through an analog command interface, allowing it to pair with analog motion cards already used in the machine. Thermal management is provided by a built-in air blower, which circulates cabinet air through the heat sink without external ducting. The power stage is rated for 40 A of continuous output, which suits medium-power servo axes in multi-axis systems. Because the cooling airflow is generated inside the unit, panel layouts can remain compact while heat is moved away from the power electronics during operation. This internal airflow supports stable heat removal without requiring a separate external fan assembly for the drive section.
The unit is part of Line 02 and is Version 1. These identifiers indicate the product generation used for this controller. Its slide-in format supports installation on shared backplanes with companion modules, and the layout matches the platform used by related drive components in the same rack. The common backplane keeps command and power coordination inside the enclosure, which is useful where several axes must respond together under one motion system. The module can therefore be used in cabinet systems that rely on a consistent physical format across multiple drive positions.
