HDS03.1-W075N-HA15-01-FW
The HDS03.1-W075N-HA15-01-FW is a drive controller engineered by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a modular cabinet alongside a power supply, it closes the control loop between higher-level motion commands and the regulated output of a connected servo or spindle motor. By converting reference signals from a CNC or PLC into precisely controlled motor current, the unit enables coordinated speed, torque, and position control on automated machining centers, material-handling lines, and assembly stations. In operation, it serves as the electrical link between the command source and the motor, adjusting output as load conditions change during acceleration, deceleration, and steady running.
The controller receives setpoint values through an analog interface, so a ±10 V command from the CNC or PLC is translated directly into motor current. This arrangement supports control systems that use conventional analog command channels. Its power stage supplies a continuous 75 A, which indicates how much torque the connected axis can sustain without thermal overload. Heat from this current is removed by a built-in air blower, so no external cabinet fan is required to keep the module within its operating range. The unit is part of the DIAX04 family, which uses common backplane connectors and parameter structures across multiple axes.
Within the production matrix, it is assigned to Line 03, which aligns mechanical spacing and connector orientation with other third-generation modules. The product functions strictly as an axis controller, separating it from supply or I/O components in the same cabinet system. Its role is limited to axis regulation, while separate modules handle incoming power conversion and other support functions. The initial release is marked as Version 1, so parameter sets should match that revision. It can be combined with other units from the HDS Drive Controllers series in multi-axis systems that use the same cabinet format.
