HDS03.1-W075N-HS72-02-FW
The HDS03.1-W075N-HS72-02-FW drive module is an HDS drive controller produced by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. It occupies a single slot in a DIAX04 automation rack and pairs with corresponding power sections to manage servo or spindle axes. The unit converts high-speed digital commands into output signals for connected motors, allowing automated machinery to maintain accurate motion during positioning and speed-controlled operation. By working with the rack power section, it helps regulate motor response during acceleration, steady running, and commanded stopping.
Communication with the motion controller relies on the SERCOS fiber-optic interface, which provides deterministic timing and electrical isolation between control layers. The drive belongs to the DIAX04 controller family, so it uses the same backplane standard as related modules in multi-axis systems. Thermal management is handled by a built-in air blower, which removes heat from the module without requiring a separate fan on the rack. For continuous operation, the power section is rated for 75 A of current, allowing it to energize medium-power servo motors when ambient temperature remains within the stated range. The optical communication path also helps reduce the effect of electrical noise on command transmission. The designation Line 03 identifies the third design line.
The module is supplied as Version 1. It converts control data into amplifier-level signals that support accurate velocity and position regulation in automated equipment. This helps the axis respond consistently during commanded starts, speed changes, and stops. Its arrangement supports orderly routing inside the rack and keeps control functions separated from the external power stage. Diagnostic handling and operating behavior follow the established module format used for this product line.
