Product Description:

Bosch Rexroth Indramat manufactures the HCS03.1E-W0070-A-05-LNNV for its HCS IndraDrive Controllers series. The unit functions as a drive controller that modulates three-phase mains power to provide precise voltage and current for industrial servo and induction motors in packaging lines, material-handling cells, and processing equipment. This allows the controller to manage speed, torque, and positioning responses in applications that require synchronized starts, stops, and load changes across connected axes. Integrated control logic communicates with supervisory PLCs to execute axis commands while monitoring thermal, electrical, and mechanical limits during operation.

The controller removes internally generated heat with internal air cooling provided by an integrated blower, so extra ventilation for the controller itself is not required inside the cabinet. During acceleration or shock loads, it can deliver a device peak current of 70 A, which supports short overload events without an immediate trip. Its input section accepts three-phase supplies from 400–500 V AC (+10%/-15%), matching common plant distribution levels. The housing carries an IP20 ingress rating, which provides finger-safe protection when mounted inside a closed control cabinet. Depending on motor selection and cycle demands, the power electronics cover a range from 15–75 kW, allowing one hardware frame to support different axis sizes across the same machine.

The controller is Version 1. Within the type code, the frame tag HCS03 identifies the mechanical platform, while voltage code 05 places the unit in the 500 V class used by the DC-bus section. The power stage supports infeeding and fed operation, so the device can operate as a regenerative supply or as a downstream drive, and multiple axes can share recovered energy over a common bus. That shared-bus arrangement lets braking energy from one axis support another axis during deceleration and speed changes.
