HDS03.1-W075N-HA32-01-FW
The HDS03.1-W075N-HA32-01-FW drive controller is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Within an automation cell, this unit acts as the power and regulation module that links a DIAX04 motion group to servo motors, converting command signals into precisely modulated output for position or velocity loops. It is intended for cabinet installation where centralized control of multiple axes is needed, and it provides the electrical interface between higher-level PLCs and the motor windings. The controller regulates motor current so connected axes can respond accurately to changing motion commands during synchronized machine operation. Because the power stage and control interface are housed in one module, wiring between the motion rack and the motor circuits remains concentrated in the control cabinet.
Electrical capability includes a continuous output rating of 75 A, allowing the controller to energize medium-to-large servo stages through repetitive load cycles without immediate current reduction. Thermal stability is maintained by a built-in air blower that circulates cabinet air directly through the heat sink fins, so no auxiliary ducting is required. This cooling method supports dense cabinet layouts because airflow is handled inside the unit rather than by separate external hardware. Stable heat removal also helps the controller maintain consistent output during prolonged motion sequences and frequent acceleration changes. In current-controlled servo operation, the power section adjusts its output to match load demand while supporting accurate speed and position response from the connected motor.
The commanded velocity or torque reference enters through an analog command interface, so the input signal should follow ±10 V norms. This analog input arrangement allows the controller to accept command values from compatible external motion electronics in a direct and simple format. The unit is part of Line 03, placing it in the third design line for this model range. It is also Version 1, which marks the product generation used for this controller. These coding elements distinguish this unit from other HDS variants without repeating the same operating characteristics elsewhere in the description.
