Product Description:

The HCS03.1E-W0070-A-05-NPBV is a Bosch Rexroth Indramat drive controller that belongs to the HCS IndraDrive Controllers series. The unit conditions incoming three-phase power and modulates motor currents so motion axes follow velocity or position commands issued by a PLC or motion CPU. By integrating power conversion and closed-loop regulation in one housing, it streamlines cabinet layouts for automated machine tools, packaging equipment, and material-handling lines where repeatable motor control is required. Its control functions also let the drive respond quickly to command changes from higher-level automation during repeated production cycles.

This controller uses internal air cooling through an integrated blower, so its heat sink temperature remains within limits without external ducting. A device peak current of 70 A allows brief acceleration or braking events without saturating the power stage. The power section covers a continuous envelope of 15 to 75 kW, giving it flexibility for medium- to high-power servo or induction motors. Its mains input accepts 3 × AC 400–500 V (+10/–15%), matching standard plant distribution networks while tolerating common voltage fluctuations. This arrangement supports applications that alternate between steady operation and short periods of higher demand.

An enclosure protection class of IP20 means the terminals must be installed inside a control cabinet while remaining accessible from the front. The power section uses an infeeding and feeding topology, so regenerative energy can be returned to the DC bus or shared among multiple axes. That arrangement can simplify energy sharing in multi-axis systems that operate from a common DC link. The product is version 1. The drive logic and power components follow the coding scheme of the HCS03 line, and the supply section uses voltage code 05. These identifiers help distinguish the electrical class and internal arrangement of the unit within the product range.
