HDS04.1-W200N-HA36-01-FW
Bosch Rexroth Indramat manufactures the HDS04.1-W200N-HA36-01-FW, an axis drive controller in the HDS Drive Controllers series. The module slots into a DIAX04 rack and partners with a power section to manage the stator current of a servo motor. By decoding reference values from upstream automation equipment, the controller supplies closed-loop regulation of velocity and position. This role places it between the motion control CPU and the electromechanical load, allowing plant builders to implement tightly synchronized multi-axis sequences without dedicating a separate inverter for every channel.
The command channel uses an analog interface, so the setpoint is conveyed through differential voltage signals that the drive converts into digital loop variables. Being part of the DIAX04 controller family means it shares matching backplane pinouts with other fourth-generation axes in the same rack system. A continuous output capability of 200 A gives the unit the headroom required for high-torque acceleration while still keeping device temperature within limits imposed by the internal sensors. Heat is removed by a built-in air blower, eliminating the need for cabinet ducting. Mechanical alignment follows line designation 04, so the housing width and connector spacing match other modules of the same line.
Within the series, this unit is version 1, indicating the first release in this product line. It is an HDS Drive Controller, so it processes axis feedback and implements current, velocity, and position loops directly on the module. Parameter blocks and diagnostic codes mirror those used across the wider HDS Drive Controllers range, which helps maintain a consistent operating structure in related rack-based systems. The controller is intended for coordinated servo applications where regulation tasks remain on the installed axis module instead of being moved to a separate device.
