Product Description:

Bosch Rexroth Indramat produces the HCS02.1E-W0028-A-03-NNNV-AA drive controller as part of the HCS IndraDrive Controllers series. The unit functions as a closed-loop power interface between the plant's AC supply and connected servo axes, shaping current and voltage so that motors follow programmed motion profiles in automated assembly, handling, and processing stations. Because it sits between the AC line and the DC bus, the controller also manages regenerative energy, braking torque, and system diagnostics. It is designated as an HCS drive controller, emphasizing its role in multi-axis platforms.

The controller accepts a three-phase input of 3 x AC 200–500 V ±10%, allowing installation on worldwide low- or medium-voltage networks. The internal power stage covers a continuous 1.5 to 11 kW range, so one frame can support small auxiliary axes as well as moderate-power main drives. For brief load peaks, the device can deliver 28 A of current, giving headroom for acceleration or shock loads. The integrated supply concept supports infeeding and feeding, so the unit can receive or deliver DC bus energy to neighboring drives instead of needing a discrete power supply. A protection rating of IP20 provides touch-safe shielding for cabinet use while relying on the enclosure for dirt or moisture control.

Thermal management uses internal air cooling through an integrated blower, so heat is expelled directly through the housing without external ductwork. Control electronics and contactors are fed by DC 24 V from the DC bus, and the same rail engages the integrated brake transistor for dynamic energy dissipation. The hardware is identified as Design Version 1, indicating the first release level for the platform. Within the line code HCS02, this version shares mechanical dimensions and fieldbus options with other variants, simplifying cabinet layouts across different power ratings.
