Product Description:

The HDS04.2-W200N-HT79-01-FW drive controller is manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It converts DC bus energy from a matching supply module into regulated three-phase power for servo axes and serves as the command stage in automated machines. By modulating motor current and velocity loops, it supports positioning and speed control in packaging, material handling, and machining systems. This arrangement lets the drive respond quickly to changing load conditions during acceleration, indexing, and steady-speed operation. Its compact format allows it to fit within multi-axis drive cabinets without requiring a separate standalone enclosure.

Motion setpoints reach the controller through the SERCOS fiber-optic interface, providing deterministic communication with higher-level PLCs and synchronized axis updates. A built-in air blower directs airflow across the heat sinks, so no external ducting is required within the specified ambient range of +5 to +45 °C. The power stage can deliver up to 200 A of continuous output, so the supply path and cabinet layout must support high current and steady heat removal during continuous duty. The housing has an IP 10 rating, so the unit is intended for clean control cabinets where falling dirt is minimal and direct contact with internal power sections must be avoided.

Operation is permitted up to 1000 m above sea level, and installations beyond that height require current or ambient derating because reduced air density lowers cooling effectiveness. The unit can operate in machine rooms up to +55 °C when derated, and it can be shipped or stored between -30 to +85 °C without loss of normal function. Electrical insulation meets class C per DIN VDE 0110, which supports the clearances required for the switching conditions inside the drive. The controller is part of the DIAX04 family and belongs to product line 04 with version 2, matching the electrical and mechanical layout used in that platform.
