HDS03.1-W100N-HS55-01-FW
The HDS03.1-W100N-HS55-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. In an automation rack, it works between the supply section and the servo motor axes it regulates, converting motion commands into controlled motor current. This arrangement supports closed-loop operation in CNC equipment, material-handling systems, and other machines that need stable torque and repeatable speed control. Its modular layout also suits multi-axis assemblies where several coordinated drives share a common cabinet structure.
Communication with the higher-level control is carried over SERCOS through an optical ring, so cyclic command and status data are exchanged with predictable timing. The controller provides a continuous output capability of 100 A, which suits medium-power servo axes that need sustained current during normal operation. As part of the DIAX04 platform, the unit uses the same general system arrangement as related modules in the drive family. Heat is removed by a built-in air blower that moves cabinet air across the heat sink surfaces. The product is identified as Line 03 within the series.
This unit is version 1, which marks the product generation for this controller type. It uses a command communication interface for drive command exchange within the control structure, while the power stage responds to incoming motion data from the optical network. The controller is intended for spindle and positioning applications where steady regulation is required over repeated operating cycles. Blower-assisted cooling supports continuous service in enclosed machine cabinets, provided cabinet airflow is not blocked around the heat sink area. The control section regulates motor current in response to commanded motion so coordinated axes can maintain the required speed and torque behavior.
