HDS03.1-W100N-HA38-01-FW
The HDS03.1-W100N-HA38-01-FW is a drive controller module built by Bosch Rexroth Indramat for positioning and speed control tasks in multi-axis automation cells. It belongs to the HDS Drive Controllers series used in modular drive racks, where it sits between the mains supply module and the servo motor. In operation, the unit converts command signals into regulated current and voltage so the motor follows programmed trajectories with stable torque and speed response. It also monitors encoder feedback, adjusts output in real time, and relays status information to the machine PLC during coordinated motion on packaging lines, transfer stations, and machining centers. This arrangement lets the drive respond quickly to changing load conditions without interrupting the overall motion sequence.
Current handling capacity reaches 100 A, so the controller can energize high-torque motors during demanding acceleration and steady-state operation. Motion references enter through an analog command interface that connects directly to legacy process controls and other signal sources that use continuous setpoint values. Thermal management is provided by a built-in air blower that draws cabinet air across the heat sink and removes the need for external ducting. The controller is used within the DIAX04 platform, and it supervises blower speed, current sensors, and heat sink temperature so it can trigger a controlled shutdown if operating limits are exceeded.
The unit is part of Line 03 and is produced in Version 1. Within the rack, it pairs with HMS power supplies over a shared backplane for DC bus energy and status exchange between system modules. Because it is a plug-in rack module rather than a standalone drive, it relies on the system power architecture for supply distribution and coordinated operation. The backplane connection carries operating data between modules while the front section remains dedicated to drive control and monitoring. This layout supports coordinated multi-axis operation in modular drive systems.
