HDS03.1-W100N-HS91-01-FW
The HDS03.1-W100N-HS91-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It operates between the central supply module and the individual servo axes, regulating current flow and closed-loop motion behavior in CNC systems and automated assembly equipment. By coordinating axis demand over a shared DC bus, the controller supports synchronized acceleration, deceleration, and holding functions across multiple motors. In this position, it links supply energy, control commands, and motor feedback so each axis responds predictably during production.
Real-time communication is handled through the optical SERCOS interface, which transfers command values and diagnostic data with deterministic timing. The output stage can supply a rated current of 100 A, giving the controller the capacity needed for demanding servo applications with sustained phase load. Heat is removed by a built-in internal air blower, so the cabinet does not need external cooling ducts or liquid-cooling hardware for this module. This cooling method supports enclosed cabinet installations where airflow must be managed within the rack. The controller uses the established module format of the product range, which keeps installation consistent with other units in the same platform and supports organized panel layout in multi-axis systems.
The controller is part of the DIAX04 platform. It is assigned to Line 03 and Version 1, which place it within a specific product generation. These identifiers distinguish the unit from other members of the platform and keep the description of the controller clear and direct. They also separate this unit from similar controllers that may use different communication or current classes within the same platform. The device remains focused on power conversion, axis control, and communication inside coordinated servo systems that use dedicated supply and axis modules in the same rack.
