HDS05.2-W300N-HA26-01-FW
The HDS05.2-W300N-HA26-01-FW is a drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation cell, this unit functions as an axis amplifier that links a motion control processor to servo motors, providing closed-loop current and velocity regulation for coordinated machine movement. Used in packaging machinery, transfer lines, and printing presses, the controller converts DC bus energy into the three-phase output required for synchronous or induction motors while monitoring feedback for fault protection. By regulating motor current in real time, it helps the machine maintain commanded speed during load changes and short cycle transitions. This operating role supports accurate motion where repeated starts, stops, and speed changes are part of normal production.
The drive accepts motion references through a command communication interface configured as analog, so position or speed demands arrive as voltage or current signals rather than through a digital network. Its continuous output current ceiling is 300 A, enabling it to energize large torque motors without derating. Within the Rexroth modular control platform, the controller is assigned to the DIAX04 family, allowing it to share a common DC bus and diagnostic architecture with companion modules. Thermal management relies on a built-in internal air blower, which draws air through the heat sink to maintain semiconductor temperatures. Because the reference path is analog, the drive can be integrated with control systems that output conventional process signals. This cooling arrangement supports sustained operation where rapid acceleration, frequent deceleration, and repeated cycling place a heavy thermal load on the power section.
The unit is Version 2, indicating a later revision within the series. It is also part of Line 05, which sets the mechanical format, including mounting height and power terminal spacing. The selected line and version affect how the module fits into the drive assembly and how its power connections align with surrounding hardware. Rated parameters are fixed at assembly, so the drive must be matched to the appropriate mains supply, motor ratings, and safety wiring before operation. Proper matching supports stable current control and predictable response in multi-axis equipment.
