Product Description:
The Bosch Rexroth Indramat HDS03.2-W075N-HS33 is a drive controller in the HDS Drive Controllers series. Designed for closed-loop motion applications, it links power supplies with servo drives and performs axis control in assembly lines, material-handling cells, and packaging equipment. In automated equipment, it serves as the regulation stage between the power supply and the connected motor axes. The unit processes digital motion commands, adjusts output current, and monitors protective functions such as overcurrent and overtemperature during operation. This allows servo axes to follow commanded speed and torque profiles with closed-loop correction.
The controller exchanges real-time setpoints and status data over the SERCOS optical fiber interface, which supports deterministic communication in multi-axis networks. The optical fiber link also helps reduce electrical interference on the command path in dense cabinet layouts. It is part of the DIAX04 family, so it shares a common platform with related modules in the same system. The logic and power stage are rated for 75 A of continuous output, allowing the unit to supply medium-frame servomotors without derating. Heat from the switching section is removed by a built-in air blower, which supports cabinet installation where external airflow is limited. The unit is part of Line 03, which identifies its design line within the product range.
The module is version 2, indicating its revision within the product line. The HS33 option code identifies the configured drive enable logic and diagnostic messaging used by this controller. Matching supply units and interface cards can be used on the same platform, so the controller fits established multi-axis layouts. The module is intended for standard factory enclosures where ambient vibration and temperature remain within normal industrial limits. Its connector arrangement suits adjacent drive components in the cabinet.
