HDS04.2-W200N-HT70-01-FW

The HDS04.2-W200N-HT70-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. As an axis module within modular DIAX servo systems, this controller regulates motor torque, speed, and position in automated machinery; common targets include packaging lines, assembly cells, and CNC cutting machines.

Communication with higher-level PLCs occurs through the SERCOS fiber-optic interface, enabling deterministic command exchange and synchronized motion cycles. The power stage is sized for a continuous output of 200 A, so matching motors must be selected with conductors and protective devices rated for that current. Thermal energy generated by the IGBTs is removed by a built-in internal air blower, which channels cabinet air through the heat sink without external ducting. Membership in the DIAX04 controller family means firmware, parameter structure, and backplane bus connectors are shared across multiple axes, simplifying spare handling. Hardware revision 2 adds enhanced diagnostic LEDs and an updated gate-drive circuit for improved short-circuit response. This dimensioning supports continuous torque production during brief thermal peaks.

Within the family hierarchy, the controller sits in line 04, a designation that defines mechanical dimensions and mounting rails used across the cabinet. Its catalog description as an HDS Drive Controller clarifies that the unit is intended for dynamic servo control rather than simple inverter duty.  Accessory cards and parameter files also interchange freely within the wider HDS Drive Controllers series, so mixed-axis systems remain consistent during service.
