Product Description:
The HCS03.1E-W0070-A-05-NNNV is a drive controller manufactured by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. Classified as an HCS drive controller, it converts line power into regulated motor voltage and manages feedback so motion axes follow programmed profiles. In automated cells, the unit coordinates torque production, braking, and safe shutdown, acting as the compact interface between plant control networks and compatible servo or induction motors. This arrangement lets the connected drive system respond quickly to load changes during positioning, speed control, and deceleration. By integrating power electronics, logic supply distribution, and a brake transistor, it reduces panel wiring and supports straightforward setup in packaging, printing, and material-handling machines.
The controller accepts a three-phase mains input of 3 × AC 400…500 V +10 %, –15 %, so it can be connected directly to common factory power systems without an external transformer. Internal airflow is provided by internal air cooling with an integrated blower, which removes heat from the power section during operation. The enclosure is rated IP20, so the unit is finger-safe but must be installed inside a closed electrical cabinet. Proper cabinet airflow still matters because the blower moves heat through the controller rather than out of the enclosure. For short acceleration bursts, the power stage can deliver a peak current of 70 A, while continuous operation must stay within a power range of 15 to 75 kW.
The energy interface uses infeeding and regenerative operation, allowing deceleration energy to return to the DC link instead of being wasted as heat. The unit uses DC 24 V from the DC bus for low-voltage control circuits and includes an integrated brake transistor. This arrangement simplifies low-voltage distribution inside the panel and supports shared DC-link operation during axis braking events. The controller belongs to the HCS03 line series and has design version 1, which sets the connector layout for this build. Voltage code 05 matches the specified mains class and completes the electrical configuration.
