Product Description:

The HCS03.1E-W0280-A-05-NNBV is a drive controller produced by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. The unit belongs to the power-electronics section of an IndraDrive system and governs motor torque, speed, and positioning by converting three-phase mains power into a regulated DC link and modulated inverter output. As an HCS drive controller, it is intended for coordinated motion axes in packaging lines, material-handling stations, and general factory automation where synchronous and induction motors must be controlled by a centralized platform.

Its mechanical build is identified as design version 1. Thermal management is handled by internal air cooling through an integrated blower, and the embedded fan channels room air across the heat sink so separate cabinet airflow is not required. The housing carries an IP20 rating, which provides finger-safe protection and requires installation inside a control enclosure. On the mains side, the controller accepts 3 × AC 400 to 500 V (+10%, -15%), accommodating common industrial power grids while tolerating normal supply variation. Power modules spanning 15 to 75 kW can be coupled to this frame size, allowing the same platform to support medium-to-large servo axes without changing the overall control concept.

In operation, the energy path uses an infeeding and fed configuration that permits several drives to share one rectifier and redistribute braking energy over the DC bus. Control electronics are sustained by 24 V DC from the DC bus, which removes the need for a separate low-voltage supply while the link remains active. Parameter data corresponds to voltage code 05, keeping device settings aligned with the high-voltage segment of the product family. Within the HCS03 line, these attributes provide standardized mounting dimensions and connection layouts for multi-axis cabinet assemblies.
