HDS05.2-W300N-HS65-01-FW
The HDS05.2-W300N-HS65-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. In a multi-axis rack, it acts as the power and regulation stage for servo and main spindle drives by converting DC-bus energy into commanded motor current. This allows connected axes to accelerate, hold speed, and stop in step with motion commands from the machine control. By processing digital setpoints from the higher-level control, it produces current output that keeps motor response aligned with the programmed motion profile. It is suited for automated systems such as presses, packaging lines, and gantries where coordinated motion is required across several axes.
For real-time coordination with a PLC, the controller communicates over SERCOS through a fiber-optic interface. This communication link carries position, velocity, and diagnostic data with deterministic timing, which helps maintain synchronized axis behavior across the drive system. The power stage can deliver a continuous output of 300 A, which supports high-torque motors used in demanding applications. Thermal loads are managed by a built-in air blower, which moves cabinet air across the heat sink and helps maintain stable operation. The unit is part of Line 05, identifying its design line within the series and matching the mechanical format used in compatible racks.
The controller belongs to the DIAX04 family and is supplied as Version 2. Parameters are loaded through the service channel before startup, and the unit shares a common DC bus with adjacent drives in the rack. Regenerated energy is dissipated through external resistors rather than inside the controller. Drive status, error history, and measured current values are stored in nonvolatile memory so operating data remains available after power is removed. Stored operating data can be reviewed after shutdown to support fault analysis, and the shared DC-bus arrangement allows neighboring modules to exchange energy during changing load conditions.
