HDS05.2-W300N-HA04-01-FW
The HDS05.2-W300N-HA04-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Mounted beside supply and I/O modules, it translates command signals into regulated motor currents that drive synchronous or induction motor axes. By managing feedback loops for torque and velocity, the unit coordinates motion sequences in machine tools, printing lines, and material-handling cells where precise, repeatable positioning is required. Its housing slides into a single slot in a 19-inch rack, which helps conserve cabinet space and supports centralized diagnostics across the drive system.
Command communication is handled through an analog interface, so velocity or torque setpoints arrive as ±10 V signals that the internal processor samples at high speed. This arrangement suits systems that use conventional reference signals instead of network-based commands. The power section is rated for 300 A, which is the continuous current the unit can supply to a motor without overheating. Thermal energy is removed by a built-in air blower, reducing dependence on cabinet fans and helping maintain stable internal temperature. The controller belongs to the DIAX04 family, so it connects to shared supply, logic, and feedback modules used across that platform. Its designation as Line 05 identifies the connector layout and performance tier used for mid-range servo axes.
The controller is Version 2, and this revision includes expanded error logging and finer resolver evaluation for more stable speed regulation during load changes. Power flows along a common DC bus that is forwarded through the backplane, allowing scalable multi-axis assemblies without additional wiring between neighboring slots. The shared backplane arrangement also keeps the rack layout compact while supporting coordinated operation between adjacent modules.
