HDS04.1-W200N-HA18-01-FW
The HDS04.1-W200N-HA18-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation cell, it links the system power stage to servo or main spindle axes and regulates the current and speed loops required by the connected motor. By processing reference values from higher-level motion controls, it converts commanded motion into stable electrical output for machining centers, printing lines, and material-handling equipment. That role makes it suitable for centralized drive cabinets where several axes must respond predictably to coordinated motion commands and changing load conditions.
This unit exchanges setpoints through an analog command interface, so velocity or torque references are transmitted as voltage levels rather than serial fieldbus frames. Because the command channel is analog, response is shaped by the connected control electronics without dependence on a network communication cycle. It belongs to the DIAX04 platform, which uses a consistent module layout across controllers of similar rating. Thermal management relies on a built-in air blower that pulls cabinet air through the heat sink to remove heat from the power electronics. The controller is part of Line 04 and has a continuous output capability of 200 A, allowing it to supply large permanent-magnet or induction motors during demanding operating cycles.
The product type is HDS Drive Controller, and the unit is version 1. Internal cooling reduces the need for added ducting around the drive section, although normal cabinet ventilation is still needed to carry heat away from nearby components. The analog reference channel is useful in systems that retain original motion cards or other voltage-based control hardware. It fits applications that require high motor current, direct analog command input, and compact enclosure layouts while keeping the control structure straightforward.
