Product Description:

The HCS03.1E-W0150-A-05-NPBV is a controller from the HCS IndraDrive Controllers series manufactured by Bosch Rexroth Indramat. It is used in industrial automation to regulate torque, speed, and position for connected servo and induction motors within multi-axis machinery. By converting three-phase mains power into a controlled DC link and modulated pulse output, the unit coordinates drive functions, diagnostics, and safety interlocks for production lines, packaging cells, and material-handling systems.

This model relies on an integrated blower, so it uses internal air cooling, which circulates cabinet air through heat-sink channels without external ductwork. During rapid load changes, the power section can deliver a device peak current of 150 A, allowing short bursts of high torque without triggering overcurrent shutdowns. The enclosure carries an IP20 ingress protection rating, meaning live parts are shielded from finger contact, but the controller must be mounted in a closed cabinet for dust protection. For compatibility with factory mains, the supply window spans 3 × AC 400…500 V +10%, -15%, so the drive tolerates typical line fluctuations encountered in 400 V and 480 V plants. Across this voltage range, the power electronics support an output power band of 15–75 kW, enabling the same frame size to serve mid-sized conveyors through large pumping stations.

The power section supports infeeding and regenerative operation, which means it can either draw energy from the grid or return regenerative energy to a shared DC bus. The unit is Design Version 1, which identifies the first layout used for this model and must match the installed option modules. The unit uses Voltage Code 05, aligning the control logic and motor parameters with the 400 to 500 V category drives in the series. Documentation and service resources from Bosch Rexroth Indramat use the same diagnostic structure across the HCS03 product line.
