HDS03.1-W075N-HA09-01-FW
The HDS03.1-W075N-HA09-01-FW is a drive controller manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It mounts on a DIAX04 backplane and converts DC bus power into controlled three-phase output for servo and spindle axes, allowing precise velocity, torque, and position control in automated machining centers and assembly lines. By combining command processing, current regulation, and diagnostic functions in one housing, the unit reduces the need for separate amplifier stages and helps simplify wiring in multi-axis cabinets. This arrangement supports centralized drive layouts where several axis modules share a common rack and power structure.
Control references enter the unit through an analog command interface, so speed or torque demands are supplied as proportional voltages that can be generated by PLC analog outputs. Thermal management is handled by a built-in air blower, and the integral fan pulls air across the heat sink so the controller can maintain continuous output without external ducting. That output reaches a rated current of 75 A, giving the module the capacity needed for medium-to-large motors at full load. Its power and fiber connections align with companion supply modules on the same rack, which supports orderly integration in a multi-axis system and keeps cable routing predictable inside the enclosure.
The unit uses the HA09 configuration. It is part of Line 03 and is released as Version 1. These identifiers distinguish the controller within the product line and indicate its place in this release sequence for the HDS platform. The rack-mounted format also keeps placement consistent with compatible modules already used in the same drive system, and the module remains intended for cabinet installation alongside matching supply and control components.
