Product Description:

The HDS03.2-W100N-HA36-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It converts command signals into controlled motor current so automated equipment can follow the requested motion profile with stable torque and speed control during indexing, positioning, and continuous travel. Power electronics, regulation circuits, and status monitoring are integrated in one housing, which helps simplify cabinet layouts for multi-axis production equipment. That arrangement reduces the need for separate control hardware inside the cabinet and keeps the axis package concentrated in a single rack position. The design suits DIAX04 rack systems used on production lines that cycle frequently and remain under load for long operating periods.

Communication with the axis board is handled through an analog interface, so velocity or torque references are transmitted as continuously variable voltage or current signals rather than serial data. Because the reference is analog, the controller responds directly to changing command levels from the upstream control circuitry. Within the DIAX04 platform, the module has a nominal current rating of 100 A, which requires properly sized supply conductors and protective devices for continuous operation. Heat from the switching section is removed by an internal air blower that moves air through the heat sink without external ducting. This cooling method supports multi-shift duty and helps maintain stable thermal conditions when the controller is driving demanding axes.

The module is Version 2, so it uses the parameter set assigned to the second release of this drive type. It is also part of Line 03 in the product range, which identifies its design line within the platform. The unit shares mounting rails and bus bars with neighboring motion modules, allowing orderly installation in standard rack layouts. The shared mechanical format also helps maintain consistent connector spacing across the rack. This arrangement supports compact cabinet organization where several axes are installed side by side.
