HDS03.2-W075N-HA22-01-FW
The HDS03.2-W075N-HA22-01-FW is a servo drive control module produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It forms the power and regulation stage between a DIAX04 multi-axis motion system and the connected motors, converting incoming DC bus energy into controlled three-phase output. In industrial automation, this controller provides closed-loop speed and torque regulation for machining centers, handling robots, and packaging equipment where coordinated motion across several axes is required. By regulating motor current from the shared supply, the unit supports synchronized starts, stops, and speed changes across linked machine sections. The drive can react quickly to command changes while keeping motor operation stable during continuous process movement.
The controller exchanges command signals over an analog command interface, allowing straightforward ±10 V velocity or torque references from legacy or modern CNC hardware. This arrangement suits systems that use direct analog motion commands instead of serial network control, and it supports simple integration with existing machine electronics. Thermal management is handled by a built-in air blower, which draws cabinet air through the heat sink so no external ducting needs to be added. Power capability is supported by a continuous output of 75 A, enabling the module to energize medium-to-large servomotors without current foldback during long acceleration ramps. The airflow path helps move heat away from the power section during sustained demand inside enclosed control cabinets.
The unit is part of Line 03, which identifies the mechanical platform size used by this controller. It is Version 2, indicating an updated logic and gate-array revision. The module mounts on the same backplane used by related HDS units, so it fits established DIAX cabinet layouts without requiring a different installation method. This format supports shared system modules and organized axis placement in multi-axis cabinets. The controller is intended for applications that need consistent drive behavior across several coordinated axes.
