Product Description:

The HCS03.1E-W0280-A-05-LNBN is a drive controller from Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. Acting as a programmable interface between the three-phase mains and connected motors, it regulates torque, speed, and position loops in automated machinery. Integrated diagnostics, coordinated axis functions, and regenerative capability allow the unit to support packaging lines, material-handling stations, and processing cells where controlled motion and energy efficiency are required. This arrangement lets the controller respond to changing load demand during acceleration, steady running, and deceleration while maintaining controlled motor behavior.

This controller uses internal air cooling, and airflow moves through built-in channels to keep semiconductors within limits without external fans. An enclosure rating of IP20 means the housing blocks objects larger than 12.5 mm, so the unit must be installed inside a cabinet. The mains connection accepts 3 x AC 400...500 V +10%, -15%, which allows tolerance for typical plant supplies while still providing full output. Within that supply range, the inverter delivers 15 to 75 kW, allowing one frame to cover several motor sizes. The DC bus is designated for infeeding or fed operation, so the unit can return regenerated energy to the line or be supplied by a separate rectifier in multi-axis groups.

The unit is Design Version 1, which corresponds to the first electronic release of this platform. Its line designation is HCS03, identifying the frame class used for this controller and the associated module range. The embedded code 05 matches 400 to 500 V applications in this product line. The unit is classified as an HCS Drive Controller, indicating the controller type used within the series. These identifiers help separate the electrical class from the mechanical platform when the controller is selected for a cabinet layout.
