HDS03.1-W100N-HS04-02-FW
The HDS03.1-W100N-HS04-02-FW is a drive controller manufactured by Bosch Rexroth Indramat and placed within the HDS Drive Controllers series. It supplies regulated power and closed-loop command handling to synchronous and induction motors used in industrial automation cells, presses, and handling equipment. By coordinating motor torque and velocity through field-oriented control, the unit acts as the interface between the machine control system and the mechanical axis. That arrangement supports precise speed regulation and stable torque delivery when the axis must respond quickly to changing load conditions.
The controller delivers a continuous output of 100 A, allowing it to operate motors that require high torque during acceleration and braking. Data exchange with the master PLC is established through the SERCOS interface, which transports setpoints, status words, and parameter data over a fiber-optic ring at deterministic cycle times. This communication method supports synchronized command execution across multiple axes in the same motion system. Thermal management is handled by a built-in air blower, which draws cabinet air across the power semiconductors to keep temperatures within the intended operating range. The unit is part of Line 03 and the DIAX04 platform, so it uses the mechanical format and connection style common to companion modules in the rack.
The unit is an HDS Drive Controller and it is Version 1. It shares a common backplane bus with adjacent axes, which supports modular installation in multi-axis assemblies and keeps the rack layout consistent from one axis position to the next. Rack-based installation also keeps wiring paths short between neighboring modules. The housing layout also follows the series mounting pitch, so additional modules can be arranged in the same cabinet structure without changing the basic mechanical format. It does not include an integrated power supply or brake resistor, and power distribution is handled through the DC-link bus together with separate system components.
