Product Description:

The HCS03.1E-F0350-A-05-NNBV is an AC drive controller manufactured by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. Within an automation cell, it regulates three-phase induction or synchronous motors by modulating the DC-bus energy that feeds the inverter stage. By converting mains power into controlled output voltage and frequency, the unit serves as the axis supply element for coordinated motion and positioning tasks in packaging, printing, and material-handling equipment.

The controller carries an enclosure classification of IP20, which means live parts are finger-safe but the device must be mounted inside a cabinet for dust and moisture protection. It accepts a mains window of 3 × AC 400…500 V +10%, -15%, so it can be connected directly to standard 400 V or 480 V plant supplies without an autotransformer. Connected loads may fall anywhere inside the 15 to 75 kW continuous power range, which supports a broad span of motor sizes and torque demands. The integrated supply section has infeed and shared DC-bus feed capability, so it can draw power from the line and return regenerated energy to a shared DC link. The hardware is identified as Design Version 1, which indicates the product’s design revision.

The HCS03 line code groups the mechanical dimensions, cooling geometry, and connector positions for this frame size. A separate field lists Voltage Code 05, and this code matches the internal insulation clearances to the specified supply level. Control electronics, encoder power, and I/O are sustained through a bootstrap rail that provides DC 24 V from DC-Bus, eliminating the need for an external logic supply during normal operation. The unit is classified as an HCS Drive Controller, which distinguishes it from power extension or regenerative modules in the same product range.
