Product Description:

The HDS04.1-W200N-HT11-01-FW is a modular axis drive unit produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a DIAX04 automation rack, the unit forms the central link between a motion controller and the individual power sections that energize servomotors or spindle drives. By translating high-level motion commands into regulated DC bus power and diagnostic feedback, it supports coordinated acceleration, deceleration, and precise positioning across multiple machine axes in CNC machining centers, high-speed printing lines, and material-handling gantries. This role allows the controller to coordinate axis response during speed changes, dwell periods, and position corrections commanded by the machine control.

For field integration, the controller exchanges real-time data over the SERCOS fiber-optic ring, providing deterministic command latency and shared timing across all axes. It belongs to the DIAX04 platform and is part of Line 04, which sets its mechanical width, backplane connector pitch, and allowable module combinations inside the rack. Continuous output capability reaches 200 A, giving the rack sufficient current for large torque bursts without derating. Heat produced by that current is removed by a built-in air blower, so no external fan tray is needed.

The drive controller is Version 1. It is classified as an HDS Drive Controller and distributes regulated DC power to attached drive cards, closing the electrical loop between the motion CPU and the motor windings. Residual heat is handled by rack ventilation during operation, and the unit uses the same startup sequence as other axes in the rack. The module also passes control and diagnostic data through the rack structure while maintaining the timing needed for coordinated multi-axis motion.
