Product Description:

The HCS03.1E-W0070-A-05-NNBV-AA is a drive controller produced by Bosch Rexroth Indramat as part of the HCS IndraDrive Controllers series. Classified under the HCS Drive Controller product type, it converts three-phase plant power into a regulated DC link and controlled motor outputs. The module supports coordinated motion commands from higher-level automation systems, so it is used in conveyor sections, gantry axes, and other industrial motion stations where synchronized movement is required. Its internal topology follows the HCS03 line architecture, and the voltage code 05 indicates adaptation to industrial mains segments used in factory environments. The controller is intended for applications that need integrated power conversion and controlled motor operation within a compact drive platform.

Thermal management is handled by internal air cooling through an integrated blower, so installation does not require cabinet ducting and the electronics remain within their rated temperature range. During dynamic load steps, the inverter can deliver a device peak current of 70 A, allowing brief torque surges without tripping. The housing carries an IP20 protection code, which is intended for mounting inside a closed control cabinet while remaining accessible for wiring. The mains input window of 3 x AC 400...500 V +10%, -15% connects the controller directly to typical factory supplies, and its continuous output capability spans 15 to 75 kW, covering medium-power pump, press, and transfer applications. The closed-cabinet construction is suited to installations where contact protection is provided by the enclosure rather than by the drive housing itself.

The power section operates in an infeeding or fed mode, so it can either return regenerated energy to the AC line or draw energy from an upstream supply module. This supports shared energy flow in multi-axis systems during braking and acceleration events. Within the HCS03 family, the controller is identified as Design Version 1, indicating the first design release for this configuration. The control electronics receive auxiliary power through DC 24 V from the DC bus, which removes the need for a separate low-voltage supply. This arrangement helps keep control functions available when the main power stage is de-energized.
