Product Description:

The HCS03.1E-W0070-A-05-NNNV-AA is an HCS Drive Controller manufactured by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. Acting as a regenerative power module, it converts plant-level three-phase energy into the controlled DC and PWM outputs required by servo and induction motors. The unit is deployed in material-handling stations, pick-and-place gantries, and other automated cells where coordinated motion sequences depend on deterministic current and voltage regulation. It is intended for machines that require controlled acceleration, braking, and stable power delivery during repeated duty cycles.

Within the HCS03 line, the controller accepts a three-phase input of 3 × AC 400…500 V (+10 %, –15 %), allowing direct connection to 480 V factory networks without intermediate transformers. Its drive section covers a continuous output span of 15 to 75 kW, allowing a single platform to serve applications from medium conveyors to high-inertia spindles. During acceleration or braking, the IGBT bridge can deliver up to 70 A of peak current, permitting short overloads without tripping. An enclosure rating of IP20 provides basic finger protection, so installation inside a switchgear cabinet is required to limit exposure to dust and accidental contact.

Heat is removed by internal air cooling that drives fresh air across the heatsink with an integrated blower, eliminating external ductwork. Control electronics use a DC 24 V supply, and the same power path supports the brake transistor during dynamic energy dissipation. The power section supports infeeding and feeding operation, so surplus kinetic energy can be returned to the mains or shared with neighboring drives on the same bus. This arrangement supports coordinated energy management when several axes operate from a shared DC bus. The unit uses voltage code 05 and is marked as design version 1.
