HDS03.1-W075N-HA14-01-FW
The HDS03.1-W075N-HA14-01-FW is a servo drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an industrial automation cell, this device sits between the central motion processor and the motor, converting command references into timed gate signals that regulate current delivered to each phase. It provides closed-loop regulation, monitoring, and protective shutdowns so packaging lines, transfer presses, or machining centers maintain repeatable axis positions. By combining power electronics with onboard status reporting, it reduces the need for separate amplifier and interface hardware in the cabinet. It can support servo or spindle applications that depend on stable current control during acceleration, holding, and deceleration.
Command signals enter through an analog reference channel that accepts ±10 V or 0–20 mA input levels used by many legacy controllers. This allows the unit to interface with older motion hardware without additional signal conversion modules. The module ties to the DIAX04 backplane so shared DC buses and diagnostic handshakes are established without extra cabling. Heat produced by the power stage is removed by a built-in air blower, allowing continuous operation when mounted in a sealed rack. The output bridge is rated for 75 A, supplying enough current for mid-frame synchronous or induction motors in coordinated motion systems.
Within the product hierarchy, the unit is part of Line 03 and is released as Version 1. Classified as an HDS Drive Controller, it couples directly to supply modules where short-circuit sensing, brake control, and axis-enable signals are processed. The module format supports installation in multi-axis control cabinets where coordinated power distribution is already present. These identifiers place the unit in the correct product group and revision level. Its operation remains focused on current regulation, protective monitoring, and coordinated motion control in multi-axis installations.
