Product Description:

The HDS04.2-W200N-HS77-01-FW drive controller is built by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It serves as an axis amplifier for servo applications, regulating current and velocity loops so connected motors follow commanded trajectories in machining centers, transfer systems, and material-handling gantries. In a multi-axis machine, the unit converts DC-bus energy into controlled motor current for precise torque and speed control. This supports repeatable motion during frequent acceleration and deceleration cycles. Its modular format allows it to operate as one axis within a coordinated rack, where matched system components handle shared power distribution and control functions.

Communication with the supervisory PLC is carried out over the SERCOS fiber-optic bus, providing cyclic setpoints and feedback with deterministic timing. The controller provides a nominal output of 200 A, allowing it to support axes with high current demand. Thermal energy from the output stage is removed by a built-in air blower, which supports heat sink cooling without external cabinet fans. Forced airflow helps move heat away from the power semiconductors during sustained operation. The controller is part of the DIAX04 platform, and the product is assigned to Line 04 within that family.

The unit is identified as Version 2, which aligns connector spacing and module interfaces with compatible later rack assemblies. As an HDS Drive Controller, it works with matching power supplies and auxiliary cards in coordinated multi-axis systems. It occupies one slot in the modular rack and relies on the surrounding system modules for the shared power architecture. Parameter access is handled through the fiber-optic link, which reduces the need for separate signal wiring to the axis module. Controlled airflow through the housing keeps internal components within their operating range when adjacent modules are installed close together.
