HDS03.1-W075N-HA02-01-FW
The HDS03.1-W075N-HA02-01-FW is a drive controller assembled by Bosch Rexroth Indramat for the HDS Drive Controllers series. In multi-axis automation racks, it regulates the power stage that drives a connected servo motor, receiving reference values from a higher-level motion processor and issuing controlled three-phase output to the motor. Its modular design allows the unit to sit beside matching supply modules in coordinated rack layouts used for packaging, printing, and machine-tool stations. This operating role supports precise torque and speed regulation on axes that must follow commanded motion without unstable current delivery.
The drive has a rated continuous output of 75 A, allowing the module to energize medium-frame servo motors without external boosters. Command data reach the control board through an analog setpoint interface, which accepts ±10 V velocity or torque references from legacy CNC or PLC hardware. Because this reference method uses conventional analog signals, the controller can work with control platforms that do not rely on digital fieldbus commands for axis regulation. Thermal control depends on a built-in air blower that pulls cabinet air across the heat sink, so supplementary ducting is not required. Airflow across the cooling surfaces helps carry away heat produced during continuous servo operation and repeated load changes.
The unit is part of Line 03, placing it in the third design line used for this product family. It is aligned with the DIAX04 family, so it uses compatible bus rails and matching supply modules in a rack installation. That alignment helps the controller fit into established cabinet layouts where related modules share the same mounting and interconnection approach. The drive is supplied as Version 1, which identifies the initial release of this configuration within the product line.
