Product Description:
The HCS03.1E-W0070-A-05-NNBV is a drive controller produced by Bosch Rexroth Indramat and positioned within the HCS IndraDrive Controllers series. As an AC-mains-powered inverter, it regulates speed, torque, and position loops for servo and induction motors in automated machinery, linking each motion axis to higher-level PLCs while feeding stabilized DC-link energy to companion drives. It supports modular cabinet layouts where multiple axes share a common power rail, a design choice that reduces wiring complexity and shortens setup time on production lines.
Within the HCS03 line, the controller delivers up to 70 A of device peak output for acceleration or regeneration events. It is supplied from 3 x AC 400…500 V +10%, -15% utility power, matching standard three-phase networks without an autotransformer. The power electronics cover a continuous envelope of 15 to 75 kW, allowing a single unit to handle medium-sized extruder, gantry, or press drives before current derating applies. Heat is removed by internal air cooling through an integrated blower, so cabinet air circulates through the heat sink and no external duct is required. The enclosure has an IP20 rating, so the unit is intended for installation inside a protected cabinet.
Configuration data provide further detail. Design version 1 indicates the component layout used for this controller, while voltage code 05 identifies the internal power section for the 400 V class mains. The integrated power supply unit supports infeeding and fed operation, allowing the device to draw energy from and return regenerative power to a common DC bus without extra modules. Control logic and I/O are maintained by an auxiliary supply of DC 24 V from the DC bus, eliminating separate supplies and preserving diagnostics during short mains interruptions.
