Product Description:

The HDS04.2-W200N-HT71-01-FW is a module in the HDS Drive Controllers series manufactured by Bosch Rexroth Indramat. Within a multi-axis rack, the unit functions as a regulated power stage that translates network commands into accurate motor currents for industrial automation lines. In automated equipment, it converts DC-bus power into controlled output for servo and spindle motion. By providing precise torque and speed control, it serves machining centers, packaging machines, and conveyor cells that require synchronized motion. Its role in the rack is to supply finely regulated phase current so commanded motion profiles can be followed with repeatable accuracy. The control section responds to changing load conditions so axis performance remains stable during acceleration, deceleration, and steady running.

The digital command communication interface is SERCOS, so the drive exchanges real-time setpoints and feedback over a fiber-optic ring. This link supports fast cyclic data transfer between the drive and the motion controller. The optical network also reduces susceptibility to electrical noise in cabinets with high switching currents. A continuous output capability of 200 A enables it to drive large servo or spindle motors without external current boosters. Thermal management is handled by a built-in air blower, which forces air across the heat sinks inside the housing. The controller is part of the DIAX04 family, so it fits with other modules that use the same backplane bus and supply unit.

The unit is part of Line 04, which matches the mechanical dimensions and connector placement used with corresponding power supplies. It uses Revision 2 control logic and diagnostic routines for this model. Shared status LEDs and I/O pinouts align it with other axes in the rack without changing the basic operating layout. Forced-air cooling lets the drive maintain rated performance when mounted side by side in dense racks, provided unobstructed internal airflow remains available through the blower path. Clear airflow through the housing helps the power section remove heat during extended operation at high load. Adequate spacing at the intake and exhaust openings helps the blower move air evenly across the internal heat sinks.
