Product Description:

The HCS03.1E-W0150-A-05-NNNV-AA is a drive controller built by Bosch Rexroth Indramat and assigned to the HCS IndraDrive Controllers series. It regulates three-phase servo and induction motors, providing closed-loop speed and torque control for automated machinery and material-handling stations. By coordinating motor currents and voltages, the unit acts as the central interface between incoming plant power and the mechanical axis it drives, converting electrical energy into controlled motion as commanded by a PLC or motion processor.

This controller handles a peak output of 150 A, allowing short bursts of high current for rapid acceleration or load changes. The housing is rated IP20, so the device is intended for installation inside an electrical cabinet. The power section is supplied from a mains window of 3 × AC 400…500 V +10 %, −15 %, which accommodates typical plant voltage fluctuations without derating. Continuous mechanical output is supported across a range of 15 to 75 kW, so the same hardware frame can serve multiple machine sizes. Thermal management relies on internal air cooling provided by an integrated blower that circulates cabinet air through the heat sink fins to remove switching losses.

The unit belongs to the HCS03 line and is design version 1, which keeps it dimensionally compatible with matching accessories and mounting rails. Its power supply section operates in an infeeding and regenerative configuration, meaning it can draw energy from the mains and return regenerative energy to the shared DC bus. Low-power electronics, gate drivers, and sensors obtain auxiliary power from a dedicated DC 24 V supply derived internally from the bus, and the integrated brake transistor supports controlled deceleration. The voltage selection for the main stage is encoded by the value 05.
