HDS02.1-W040N-HA34-01-FW
The HDS02.1-W040N-HA34-01-FW is a drive controller manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series. It is used in multi-axis machining centers, packaging lines, and material-handling cells, where it converts DC bus power into controlled three-phase output for servo axes. The controller acts as the power stage between the shared supply and the motor, translating command input into regulated output for coordinated machine motion. By monitoring feedback signals and adjusting pulse patterns in real time, the unit keeps motor torque and speed aligned with the commanded motion profile. This operating role supports accurate positioning and stable speed control in industrial automation systems.
Motion commands are transmitted through an analog interface, so the controller can accept direct voltage or current references from a master PLC. Because the command path is analog, it can be paired with control systems that provide simple reference signals instead of digital fieldbus communication. A continuous output capacity of 40 A supports midsize servo motors that may demand elevated current during acceleration and load changes. Heat generated by the switching devices is removed by a built-in air blower, which reduces the need for external cooling hardware and helps keep enclosure temperatures within a safe range. This arrangement supports steady operation in cabinets where several axes share the same power structure.
As part of the DIAX04 family, the unit uses the same mechanical format as companion power supplies and backplane buses in the same platform. The product belongs to Line 02, which sets its slot width and connector layout inside the drive rack. It is built as Version 1, indicating the first design iteration for this configuration. The common rack format helps preserve module alignment and electrical interfacing throughout the assembly. It also keeps wiring practices and diagnostic behavior consistent when the controller is installed with matching modules in a multi-axis system.
