Product Description:

The HDS04.1-W200N-HS79-01-FW is a drive controller manufactured by Bosch Rexroth Indramat. Installed as an axis module, it receives motion commands from a higher-level controller and converts them into regulated three-phase power for servo or spindle motors. This role lets the module translate closed-loop control demands into stable motor current during synchronized machine movement across multiple coordinated axes. In automated production lines, the unit maintains motor velocity, torque, and position so that tooling or material-handling processes run with repeatable accuracy.

A fiber-optic interface compliant with SERCOS supplies deterministic command and status frames between the controller and the motion CPU. The power stage delivers a continuous output of 200 A, giving the module enough headroom for high-inertia axes and rapid acceleration profiles. That current capacity supports sustained load changes without forcing the axis into early current limiting. Heat produced by IGBT switching is removed by a built-in air blower, so cooling is handled inside the unit. The control electronics belong to the DIAX04 family, so connector geometry and parameter structure match other members of the platform. The unit is Version 1.

The ordering code also includes layout data that clarify mounting and system matching. The slot designation Line 04 fixes the unit's height, depth, and backplane plug arrangement so it fits beside matching power supply and I/O cards. This fixed slot format helps keep adjacent module spacing and electrical mating consistent across the rack. Shared diagnostics and parameter blocks align its operation with related modules in the same system. The functional description identifies it as an active axis amplifier rather than a passive distribution or termination module that may occupy adjacent rack positions.
