HDS05.2-W300N-HS91-01-FW
The HDS05.2-W300N-HS91-01-FW is a digital drive controller produced by Bosch Rexroth Indramat. It serves as the axis amplifier in motion systems, converting low-voltage control commands into regulated motor current for industrial servos and spindles. Installed alongside other drives on a shared DC bus, the unit supports accurate speed, torque, and position control in packaging machinery, transfer lines, and machining centers. This arrangement lets one supply section support several axes while each module regulates the motor connected to its own output stage. Because the power section works from the central bus, the drive can respond quickly to changing load demand during indexing, contouring, and spindle control.
Communication with the motion CPU is handled through the SERCOS optical ring, which provides synchronized setpoint updates and diagnostic feedback without analog wiring. As part of the DIAX04 platform, the module plugs into the system backplane and can exchange energy over the shared DC bus used by adjacent axes. The output stage is rated at 300 A, which suits high-inertia loads and demanding acceleration periods. Thermal management is handled by a built-in air blower that moves cabinet air across the heat sink, so no external ducting is required for the drive itself.
The unit is Version 2 and retains the mechanical dimensions and connector positions used by this design family. The module is part of Line 05, which identifies its place within the platform's power range. Its product category is HDS Drive Controller, so it follows the naming and interface structure used across related HDS modules. This layout supports cabinet installations that group supply units, control electronics, and power sections in one modular drive assembly. The drive is intended for coordinated multi-axis systems where bus sharing and closed-loop motor control are handled within the same platform.
