HDS03.1-W075N-HA36-01-FW
The HDS03.1-W075N-HA36-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It is used in multi-axis automation racks to regulate servo and spindle drives in coordinated machine systems. The unit converts command references into controlled current and voltage for motor windings, allowing positioning, speed, and torque to remain within programmed limits during machine operation. Because the controller works as the power and regulation stage for an axis, it supports repeatable motion during indexing, feed control, and speed-regulated spindle tasks. Its rack-mounted format also allows multiple axes to operate side by side in a shared automation cabinet.
The controller can deliver up to 75 A of continuous output, giving it capacity for medium-power axes that experience repeated acceleration and changing load demand. Thermal management is handled by a built-in air blower, which moves cooling air through the heat-sink channels without the need for a separate external fan assembly. Command signals are exchanged through an analog interface, so ±10 V and 4–20 mA references from a PLC can set speed or torque in real time. The unit matches the DIAX04 platform, which supports a common DC bus and shared logic supplies across adjacent modules. This arrangement helps multiple drives operate from the same rack infrastructure while keeping signal flow and power distribution organized.
The drive is part of Line 03, indicating the third design line for this controller type. It is Version 1, which identifies the first production revision for that line. These identifiers distinguish the unit within the product range without repeating the broader series description. The controller uses the same electrical and mechanical format as neighboring modules in the rack, so it fits systems built around shared power distribution and coordinated axis control. That compatibility supports consistent integration with associated power supplies, motor feedback connections, and other modules used in the same drive platform.
