Product Description:

The HDS02.1-W040N-HS78-00-FW is a digital drive controller produced by Bosch Rexroth Indramat and it belongs to the HDS Drive Controllers series. Within an automation cell, this unit regulates current and velocity loops for servo axes that share a common high-voltage DC bus. By converting command telegrams from a central motion processor into precise PWM switching for the connected motor, the controller forms the interface between machine logic and electromechanical motion. Its compact Eurocard housing lets multiple axes occupy a single rack slot, saving cabinet space in packaging machinery, printing lines, and gantry systems.

Key technical characteristics determine integration practice. The manufacturer name Bosch Rexroth Indramat confirms compatibility with the company’s diagnostic tools. Membership in the HDS Drive Controllers series means the module mates mechanically with HMS power supplies and exchanges data over the SERCOS fiber-optic ring, providing deterministic setpoint and feedback transmission. Thermal management is handled by a built-in internal air blower, so only unobstructed airflow is required rather than external heat sinks. The unit can continuously supply 40 A of motor phase current, a figure that dictates cable sizing and establishes the maximum torque available to the connected servo under continuous load.

Several identifiers fine-tune cabinet planning and firmware selection. The controller belongs to the DIAX04 family, so it accepts firmware kernels written for that backplane and uses distributed supply monitoring present on the bus. Hardware labeling marks it as line 02, while the assembly is built to version 1, ensuring parts interchangeability during service. As an intelligent drive controller, this hardware has no alternative derivatives, simplifying spare-parts stocking. Combined with the cooling method and current rating described earlier, these identifiers help engineers match axis demands, verify SERCOS bandwidth, and allocate rack airflow without duplicating data across multiple specification sheets.
