Product Description:

The HCS03.1E-W0350-A-05-NNBV is a drive controller manufactured by Bosch Rexroth Indramat and placed within the HCS IndraDrive Controllers series. It acts as the central power interface between a three-phase mains supply and connected servo or induction motor systems by converting incoming utility power, forming a shared DC bus, and issuing commanded current to connected inverters. In automated conveyor lines, pick-and-place systems, and process machinery, it provides the controlled acceleration, braking, and holding functions required for coordinated motion.

This controller belongs to the HCS03 line, a designation tied to its frame height, mounting slots, and internal busbar geometry. Hardware revision is identified as design version 1, and the controller uses the corresponding diagnostic register order for that revision. An enclosure rating of IP20 helps prevent accidental finger contact, but the unit must be installed in a protected cabinet. The power stage accepts 3 × AC 400–500 V with a tolerance of +10/-15 percent from nominal, allowing operation on both 400 V and 460 V plant supplies. Within that input range, the converter supports a continuous mechanical output envelope of 15–75 kW, which suits mid-size pumps, presses, and gantry axes that operate under changing load conditions.

Energy exchange on the DC link is handled by an infeeding and regenerative power supply configuration, allowing surplus braking energy to be returned to the utility or shared with adjacent drives. Component scaling follows voltage code 05, so the semiconductor ratings match the 500 V class bus potential. Control electronics, I/O, and sensors draw DC 24 V supplied directly from the common bus, which reduces panel wiring. Heat produced by switching elements is removed by internal air cooling through an integrated blower, which sustains airflow without external ducts and keeps the controller compact for multi-axis rack assemblies.
