HDS03.1-W075N-HA16-01-FW
The HDS03.1-W075N-HA16-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a drive cabinet, this module serves as the power stage that works with digital feedback and power-supply units to operate synchronous and asynchronous servo motors. It converts DC bus power into controlled three-phase output for the motor windings. The controller also processes real-time motion commands so torque, speed, and position can be regulated for transfer systems, gantries, tool changers, and other coordinated automation axes. This arrangement supports closed-loop motor control where accurate response is required during changing load conditions.
Signal exchange is handled through an analog command interface. The drive accepts ±10 V setpoint signals for torque or velocity demand and returns proportional monitor voltages, which allows the axis command and status signals to be handled in a simple analog format. Its continuous output capability reaches 75 A, which supports large-frame motors during acceleration and under steady mechanical load. Thermal management relies on a built-in air blower that moves cabinet air through the heat sink, so external ducting is not required. Forced airflow helps remove heat from the power section during continuous operation.
The controller is part of the DIAX04 platform, so it follows the same general system architecture used by related axes in the rack. It belongs to Line 03 in the product range. The unit is Version 1. Its mounting geometry and connector layout match other modules used in the assembly, which helps it fit into multi-axis installations that combine supply, control, and feedback sections. The physical format supports straightforward placement beside compatible modules without changing the overall rack arrangement.
