Product Description:

The HDS03.1-W100N-H is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It forms part of a multi-axis DIAX04 rack where it converts DC bus energy into controlled three-phase outputs for synchronous and induction motors used in machining centers, printing lines, and general automation cells.

This unit can supply a continuous Rated Current of 100 A, a value that defines the maximum rms output current available to the connected motor windings under nominal conditions. Thermal control is handled by a Built-in Internal Air Blower, so cabinet designers do not need additional ducting for this module. The housing carries a Protection category IP 10, meaning the enclosure is finger-safe but must be mounted inside a closed electrical cabinet. Continuous service is specified within a surrounding air temperature of +5 … +45 °C; outside this band the controller may overheat or require de-rating. Installation without loss of performance is allowed up to 1000 m above sea level, covering most factory floors without supplemental cooling or pressurization.

If cabinet temperatures climb further, operation can still continue but the output current must be reduced once the environment reaches +55 °C. For logistics planning, the electronics withstand a non-operational window of -30 … +85 °C that protects the circuitry during winter shipping or high-temperature storage. Windings and internal conductors use an Insulation classification C rating according to DIN VDE 0110, granting elevated thermal endurance that complements the forced-air path. Integration into the DIAX04 architecture provides standardized communication interfaces and identical mounting geometry, enabling the controller to slide into existing racks alongside analog or digital drive cards without adapter plates.
