Product Description:
The HDS03.2-W075N-HS78-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. As part of an Indramat multi-axis motion package, the unit regulates current and velocity loops for servo and main spindle motors in automated machinery. It occupies the power slot in a rack and communicates with higher-level PLCs to execute coordinated positioning and speed control tasks. In operation, it converts DC-bus power into controlled motor current so commanded motion profiles can be followed during acceleration, steady running, and deceleration. Typical applications include packaging, printing, and material-handling equipment.
The controller exchanges setpoints and feedback over the SERCOS fiber-optic ring, a deterministic interface that synchronizes drives within microseconds. As part of the DIAX04 family, it shares power supply modules and backplane connections with other axes, which keeps the system layout consistent. Thermal management relies on a built-in air blower that moves ambient air through the heat sinks, so no external ducting is needed. This cooling method supports heat removal from the power electronics during sustained load operation. The continuous output capability is 75 A, allowing the device to energize medium-to-large synchronous motors without reaching current limits.
The unit is Version 2. It is part of Line 03, which matches its mechanical form factor and connector layout. These identifiers correspond to the product generation and housing arrangement used for this model. Dedicated current sensors and gate drivers shape the PWM voltage supplied by the connected power section during closed-loop operation. The controller is intended for rack-based systems that separate power supply, drive modules, and control functions into matched system components. It can be integrated with other axes in the same rack for synchronized machine motion.
