HDS03.1-W100N-HA04-01-FW
The HDS03.1-W100N-HA04-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. It regulates motor current and velocity commands in industrial automation lines where coordinated axis motion is required. By translating reference signals from a motion PLC into controlled output for servo motors, it keeps multi-axis machinery synchronized during cutting, packaging, or material-handling processes. In automated equipment, it serves as the regulation stage between the control system and the motor so commanded speed changes and current demand can be applied in a controlled manner. This role suits machinery that depends on stable axis response throughout repeated production cycles.
Command signals reach the controller through an analog interface, which means velocity or torque references are delivered as ±10 V or 0 to 20 mA levels instead of a fieldbus. This format supports systems that use direct reference wiring rather than network-based command transmission. The unit belongs to the DIAX04 controller family, and its card layout matches other axes that share the same backplane. Thermal management is handled by a built-in air blower that draws cabinet air through the heat sink to keep semiconductor temperatures within safe limits during continuous operation. The power section is rated for 100 A of continuous output current, allowing it to drive medium-torque induction or synchronous motors without derating. The unit is part of Line 03.
The controller is Version 1. The internal airflow path should be kept clear of dust so the blower can maintain cooling performance during operation. The device plugs into a common power-supply rack. It also interfaces with feedback modules to close the control loop without separate amplification stages.
