HDS05.2-W300N-HS70-01-FW
The HDS05.2-W300N-HS70-01-FW is a drive controller produced by Bosch Rexroth Indramat and placed in the HDS Drive Controllers series. As a modular unit in multi-axis racks, it converts low-level motion commands from a PLC into regulated current for servo and spindle axes. In automated equipment, it serves as the electrical control stage between the machine controller and the connected actuator. This lets the unit regulate acceleration, speed, and torque through a closed control loop. Because it is used in a rack-based system, the controller works with shared supply sections instead of operating as a standalone inverter.
Communication is handled through the SERCOS fiber-optic interface, which supports time-synchronized command and feedback exchange for coordinated axis motion. As part of the DIAX04 platform, the unit uses the same rack architecture, common backplane, and shared power infrastructure as related modules in the system. That arrangement supports deterministic interpolation across multiple axes during demanding motion sequences. The controller can deliver a continuous output of 300 A, making it suitable for high-current servo applications and large torque loads. Heat is removed by a built-in air blower, which directs airflow through the power section and supports stable thermal operation without a separate external blower.
The controller belongs to Line 05 and is built in Version 2, indicating its design generation within this product range. The HS70 function code identifies the control section used in this model, and the unit operates as an HDS drive controller with current regulation, resolver evaluation, and protective shutdown functions. This hardware revision includes updated diagnostic handling, added fault-history storage, and revised gate-driver circuitry for the power stage. The module occupies the power slot intended for its current class and matches cable sets sized for that load level. Its slot size and connection layout match adjacent rack hardware, so the unit fits the intended installation position without mechanical changes to neighboring modules.
