Product Description:

The HDS02.1-W040N-HS12-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Its designation places it in Line 02 and Version 1, which identifies the product revision used with matching supply modules. Installed in multi-axis cabinets, it converts serial motion commands into controlled power pulses that drive synchronous and asynchronous servo motors in factory automation cells. The unit combines signal processing, power electronics, and diagnostics to simplify axis integration and maintain precise motor behavior under varying mechanical loads.

Communication with the central motion CPU is handled through the optical SERCOS interface, so parameter data and real-time setpoints travel on a noise-immune ring at deterministic update rates. The power stage is rated for a continuous output of 40 A, allowing the controller to energize medium-frame motors without exceeding thermal limits. The enclosure has an IP10 rating, which keeps out solid objects larger than 50 mm while allowing cooling air to circulate freely. That airflow is provided by a built-in air blower, eliminating the need for external fans and helping maintain uniform component temperatures. Reliable operation is specified within an ambient range of +5 to +45 °C, and when the unit is not operating it can withstand storage temperatures from -30 to +85 °C.

The unit belongs to the DIAX04 controller family, so it shares back-plane bus geometry and encoder feedback wiring with other modules in that platform. Installation is approved up to 1000 m above sea level, where cooling density still supports the stated current rating. Its windings and internal wiring carry an insulation rating of class C per DIN VDE 0110, permitting higher hot-spot temperatures during peak demand cycles. When cabinet temperatures rise, performance can be derated but remains permissible until the surrounding air reaches +55 °C.
