Product Description:

The HDS02.1-W040N-HS92-01-FW is a Bosch Rexroth Indramat drive controller supplied within the HDS Drive Controllers series and aligned with the DIAX04 controller family. As an HDS drive controller, it provides axis power and closed-loop control inside modular automation racks, coordinating servo and spindle drives over the common DC bus. It regulates current and feedback signals so connected axes can maintain commanded speed and position during machine operation. This arrangement suits modular drive systems where several axes share one power infrastructure. This unit belongs to line 02 and is delivered in version 1.

Axis commands and diagnostic data are exchanged through the SERCOS fiber-optic interface, enabling deterministic communication with compatible motion controllers. The power section can deliver a continuous output of 40 A, which is used when selecting matching supply modules and motor cables. Thermal energy is removed by a built-in air blower, so no external heat sink or cabinet ducting is required. The unit has an IP 10 protection category and is intended for mounting inside closed electrical enclosures rather than in exposed machine locations. Reliable operation is permitted at ambient temperatures from +5 to +45 °C, allowing use on most factory floors without derating.

For storage and transport, the controller can withstand temperatures from -30 to +85 °C. Installation is approved up to 1000 m above sea level, and above this height the output current must be reduced because cooling becomes less effective. If enclosure temperature rises during operation, the controller can still run at a reduced load up to +55 °C. Windings, control electronics, and busbars use Class C insulation per DIN VDE 0110, supporting elevated internal hot-spot temperatures during rapid acceleration cycles. These limits matter when the drive is installed beside other power modules that add heat inside the same cabinet.
