HDS02.1-W040N-HA03-01-FW
The HDS02.1-W040N-HA03-01-FW is a drive controller released by Bosch Rexroth Indramat for the HDS Drive Controllers series. Acting as a closed-loop amplifier for servo axes, it links a shared supply module to individual motors and issues torque or velocity commands according to reference values from upper-level control logic. In this role, it converts DC-bus power into controlled motor current for precise axis response during acceleration, speed regulation, and positioning. The unit mounts in a DIAX rack next to related motion modules, allowing coordinated multi-axis operation inside packaging, printing, and material-handling machines.
At its power stage, the controller is rated for 40 A of continuous output, so medium-inertia motors can be driven without current derating. This current capacity supports steady servo operation during sustained machine cycles. Command signals arrive through an analog interface, enabling ±10 V velocity or torque references from traditional PLC analog output cards. Thermal management is handled by a built-in air blower that directs cabinet air across the heat sinks and keeps semiconductor temperatures within safe limits. Because the module belongs to the DIAX04 family, its feedback sockets and bus connectors match those found on companion axes in the same rack.
The unit is part of Line 02 and Version 1, which correspond to the correct circuit generation. Within the HDS Drive Controllers series, this line and version use standardized slot spacing, identical gate-array logic, and preset resolver scaling. The common connector layout keeps wiring patterns consistent across multiple axes, and the shared platform helps the module fit alongside related drive units without changes to the rack arrangement. That arrangement supports organized multi-axis layouts where supply, feedback, and control connections remain in expected positions from one slot to the next.
