HDS03.2-W075N-HS38-01-FW
The HDS03.2-W075N-HS38-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. The unit supplies regulated current to servo axes and supervises motor feedback signals, allowing an automation system to carry out precise position, velocity, and torque commands without separate amplifiers. Installed in a modular drive rack, it links motion commands from a fiber-optic network to the power section that energizes motors in packaging lines, machine tools, and automated assembly stations. In systems with multiple drives, it serves as the axis-specific control stage between the higher-level motion controller and the connected motor.
The controller has a continuous output of 75 A, allowing it to operate medium-power synchronous or induction servomotors without thermal derating. It belongs to Line 03, which matches the mechanical format used with corresponding supply modules in the platform, and the unit is release 2. Command data enter through the fiber-optic SERCOS interface, so position and diagnostic telegrams move between the PLC or CNC and the drive in deterministic 1, 2, or 4 ms cycles. It is part of the DIAX04 controller family, which uses the same basic module arrangement across related drives and supports consistent integration within a multi-axis rack.
Thermal management inside the chassis relies on a built-in air blower. It pushes airflow along the heat-sink fins so cabinet air can remove heat during sustained operation and regeneration. This cooling layout helps the power section stay within its operating temperature range during prolonged load changes, while the controller continues to manage current delivery and feedback processing. The airflow path also supports stable operation when several modules are mounted close together in the same enclosure.
