Product Description:

The HDS03.2-W100N-HS27-01-FW drive controller is manufactured by Bosch Rexroth Indramat and sits in the HDS Drive Controllers series. It is installed in multi-axis automation cells to control power delivery, velocity, and position for servo motors that require coordinated motion. By shaping DC-bus energy into controlled three-phase outputs, the unit enables packaging machines, gantry loaders, and machining centers to repeat cycles with high positional fidelity. The module installs on a DIN rail beside the DC supply and uses a fiber-optic link to accept synchronized motion commands. This arrangement helps the controller respond quickly to changing load conditions during acceleration, deceleration, and interpolated motion.

Communication to the supervisory control layer takes place over SERCOS, allowing time-deterministic exchange of setpoints, status words, and diagnostics. The optical ring helps keep axis updates aligned across linked drives during coordinated moves. The power section is dimensioned for a continuous output of 100 A, so the drive can energize high-inertia servomotors without external current boosters. Thermal loads are expelled by a built-in internal air blower, which draws cabinet air through the heat sink and pushes it out the top cover. The unit is part of the DIAX04 controller family, and within that platform it carries the Line 03 designation that matches its connector layout and mechanical height.

The controller is Version 2 and includes updated gate drivers with expanded fault memory over the initial release. The larger memory area allows more operating events to be retained for later review after a trip or shutdown. A dedicated command communication interface preserves deterministic timing so motion events remain synchronized even when multiple axes share the same DC bus. The internal air cooling arrangement directs airflow across the heat sink, keeping semiconductor temperatures within limits without placing extra demand on enclosure ventilation. The unit functions as an HDS Drive Controller in multi-axis systems and does not include an integrated power supply or brake resistor.
