HDS03.1-W100N-HT14-01-FW
The HDS03.1-W100N-HT14-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat as a member of the HDS Drive Controllers series. The unit functions as a power and motion interface between a central CNC or PLC and connected AC servo motors, translating digital commands into precisely metered current and voltage. Within an automation cell, it coordinates velocity, torque, and position loops so mechanical axes reach setpoints without overshoot during machining, packaging, or printing cycles. This arrangement supports closed-loop motion control in systems where multiple axes must respond quickly and remain synchronized under changing load conditions.
At the communication layer, the controller uses SERCOS fiber-optic networking, which transmits cyclic setpoints and feedback with deterministic timing suitable for multi-axis interpolation. Hardware layout follows the DIAX04 architecture, so the module slides into a common power supply rack and shares a DC bus with related drives. Thermal regulation is managed by a built-in air blower, and the power stage is rated for 100 A continuous motor current. The unit is part of Line 03, indicating the third design line used for this controller type. This combination supports coordinated motion in larger servo systems where sustained output current and stable communication are both required.
The controller is Version 1, so its hardware options and connector pinouts match the initial release documented for the series. As part of the HDS Drive Controllers range, it uses the same diagnostic LED patterns and error codes found across related motion products. The unit does not include an integrated power supply or brake resistor, so those functions are provided by separate system modules. Separating those functions allows the controller to operate within a modular rack layout where power conversion and braking are handled by dedicated companion units.
