HDS03.1-W075N-HS33-01-FW
The HDS03.1-W075N-HS33-01-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It serves as a servo amplifier module in multi-axis racks, where it converts incoming DC-bus power into regulated motor current and passes digital command data between the machine control and connected motors. In automated machinery, the unit supports coordinated velocity, torque, and position control so axes can follow programmed motion profiles in conveyor systems, packaging equipment, and metal-forming machines. Its modular format allows it to operate as part of a larger rack-based drive system rather than as a standalone amplifier.
The controller provides a continuous output of 75 A, allowing it to supply large servo axes during sustained operation without exceeding its rated current. Command data are exchanged through the SERCOS fiber-optic ring, which supports deterministic communication for synchronized motion across multiple drives. The unit is part of the DIAX04 family, so it matches the rack structure used with compatible power and interface modules. Thermal management is handled by a built-in air blower that moves cabinet air through the heat sink to control internal temperature during high-load operation. This airflow path helps remove heat from the power electronics during repeated acceleration and deceleration cycles.
The product is part of Line 03, which identifies the third design line for this controller format. It is classified as an HDS Drive Controller and is listed as Version 1. Its layout suits systems where several servo channels share a common drive platform and communicate with a higher-level controller through a centralized motion architecture. Because the controller combines power handling and motion coordination in one rack module, it fits installations that need compact drive hardware within a multi-axis cabinet.
