Product Description:

The HDS04.1-W200N-HS93-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed beside a shared power supply in a multi-axis rack, it converts bus voltage into regulated three-phase outputs that control servo motor speed, torque, and position. By using closed-loop control, it supports coordinated motion in packaging machines, printing lines, and material-handling gantries where several axes must respond to the same motion program. Its high current capability makes it suitable for axis groups that handle heavy loads or rapid acceleration cycles, especially where the drive must maintain accurate motor response during frequent starts, stops, and speed changes.

Its communication layer uses the SERCOS fiber ring, delivering synchronized telegrams for deterministic axis updates across the rack. The inverter bridge sustains 200 A of continuous RMS current, so large-frame motors can accelerate without derating during sustained operation. Peak dynamic current remains available while the common DC bus stays within tolerance, which helps the controller support short bursts of high demand during indexing or transfer moves. Thermal energy from the IGBTs is expelled by a built-in air blower, allowing cabinet designs without external ducting. Mechanical dimensions and connectors match the DIAX04 controller family, and the unit is Version 1.

The unit is part of Line 04, a power class used with matching supply modules and bus bars in the same rack system. Because command traffic uses an optical bus, electrical noise from switching devices is less likely to interfere with communication quality between the controller and the higher-level motion system. This supports stable axis updates when several drives share one enclosure and operate from a common power section. The controller is intended for modular installations where power distribution and motion control are handled through shared rack components.
