Product Description:

The HCS03.1E-W0070-A-05-NPBV-AA is a drive controller manufactured by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. It is installed in control cabinets to manage power conversion and braking energy for multiple servo axes, providing coordinated automation in conveyor, packaging, and machining lines. By combining supply regulation and onboard diagnostics, the controller ensures that connected IndraDrive inverters receive stable DC bus power while returning excess energy to the mains or dissipating it through configured resistors.

The controller accepts a mains input of 3 × AC 400–500 V +10%, -15%, covering common industrial supply networks without additional transformers. Inside the housing, an integrated blower provides internal air cooling, so external ducting is unnecessary while component temperatures remain within rated limits. Its power electronics are dimensioned for applications requiring up to 70 A of device peak current, allowing short acceleration bursts on high-inertia loads. Continuous operation is supported across a power envelope of 15 to 75 kW, enabling the same hardware type code to serve small indexing stations or large spindle groups. The enclosure carries an IP20 rating, indicating protection against solid objects larger than 12 mm while relying on a closed cabinet for enclosure protection. As an HCS drive controller, it integrates with IndraDrive control functions to monitor current, voltage, and thermal status and to trigger controlled shutdowns when limits are approached.

Energy exchange with the DC bus is handled through an infeeding and regenerative feedback topology, permitting active rectification from the mains and feedback during braking cycles. The hardware corresponds to design 1, so its mechanical dimensions and connector layouts match other HCS03 devices released under the same revision. Within the family, it is identified by the line code HCS03, and the supply section uses voltage code 05.
