HDS03.2-W075N-HA40-01-FW
The HDS03.2-W075N-HA40-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It is installed in modular drive racks to supervise power conversion and execute motion commands for a single servo axis, supplying regulated output for precise torque or speed control. In automated production lines, it regulates motor current so commanded motion remains consistent during acceleration, deceleration, and steady-speed operation. By combining power electronics, control logic, and diagnostic circuitry in one housing, the unit serves as the link between the central PLC and the mechanical load.
The command path relies on an analog reference, allowing ±10 V velocity or torque setpoints to feed directly into the controller. Continuous operation is supported by a rated current of 75 A, which sets the continuous load that the switching stage can supply to the motor. Excess heat is removed by a built-in air blower, so ambient air moves through the heat sink without requiring external fans. The module is part of the DIAX04 platform, which allows it to share a common DC bus, field supply, and fiber-optic diagnostics with neighboring axes. It is assigned to Line 03, indicating the design line used for this unit.
The assembly is classified as an HDS Drive Controller and is supplied in Version 2. This version adds expanded parameter memory and improved fault logging compared with earlier releases, which helps the controller store operating data and report faults more clearly during machine operation. The unit is used with the proper feedback connection and control hardware for the axis, and it fits the modular rack layout used by this drive family. Its combined control and diagnostic functions allow the drive to respond to incoming commands while monitoring internal operating conditions during normal production cycles.
