Product Description:

The HDS03.1-W100N-HS70-01-FW drive controller is manufactured by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. As a multi-axis control module, it links motion commands from a higher-level PLC to Indramat power sections, coordinating torque, velocity, and position loops in automated machinery and material-handling lines. Within an automation rack, it works with matching power sections to form a closed-loop drive for each servo axis. This arrangement allows the control stage and the power stage to operate together without external interface converters. By separating control electronics from the power section, the unit supports rack-based drive layouts used in packaging, transfer, and handling equipment.

Communication between this controller and the motion control system occurs over the SERCOS interface, so cyclic setpoints and feedback are exchanged on a single fiber-optic loop. Fiber-optic communication helps the system pass setpoints and status data with low susceptibility to electrical noise inside busy control cabinets. The unit handles motor currents up to 100 A, which is the maximum continuous output it can deliver to connected power modules without derating. Thermal energy is removed by a built-in air blower, allowing cabinet installation without external ductwork. The hardware follows the DIAX04 controller family, which uses standardized backplane wiring and common parameter structures across the product line. This layout suits multi-axis cabinets where synchronized command execution and steady current regulation are required.

The device belongs to Line 03 and is identified as Version 1. These identifiers place the controller within a specific release of this product line and keep the coded configuration easy to read. It is used where one controller must coordinate command exchange, current regulation, and feedback handling for several servo axes in the same machine. The module can be installed as part of an automation rack that groups related drive components in a single cabinet section.
