HDS04.1-W200N-HA34-01-FW
The HDS04.1-W200N-HA34-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat. Intended for multi-axis platforms, the unit manages power conversion and closed-loop speed control for industrial servo and spindle motors. In automated equipment, it serves as the power and control stage between the machine controller and the connected motor. This allows the drive to respond to changing load conditions while maintaining commanded motion profiles. By combining current regulation, command handling, and dedicated cooling in one rack-mounted module, it supports precise torque and speed control in machine tools, packaging lines, and material-handling systems.
For command input, the controller exchanges setpoints through an analog reference channel, so legacy PLCs can issue speed or torque commands without digital fieldbus hardware. That input method is useful in retrofit systems that still use conventional analog command signals. The unit is designed for the DIAX04 platform, which supports coordinated motion across related drive modules in the same rack. Thermal management depends on a built-in air blower, which circulates air directly over the heat sinks to remove losses created by the switching devices. The module is part of Line 04, and its bus bars are rated for 200 A of continuous output for large synchronous or induction motors. The controller is Version 1.
The unit is part of the HDS Drive Controllers series and is supplied as a complete axis module for rack installation. Its blower also helps maintain cabinet airflow by moving heat away from the power section during prolonged operation, which supports more consistent temperatures around adjacent electronics. Additional HDS axes can be connected on a common DC link, and the cabinet can keep the same basic cooling duct placement when the system is expanded.
