Product Description:

The HCS03.1E-W0280-A-05-NNBN is a drive controller manufactured by Bosch Rexroth Indramat and assigned to the HCS IndraDrive Controllers series. It serves as the central power and control element for servo or induction motors in automated production lines, converting motion commands into controlled three-phase output for connected actuators. It is suitable for coordinated motion tasks that require stable torque, speed, and position control across conveyors, handling axes, and process machinery. During deceleration, the unit can return recovered energy to the DC link instead of dissipating it only as heat.

This controller is designed for mains supplies of 3 x AC 400...500 V +10%, -15%, allowing installation on 400 V and 480 V plant power systems without tap changes. Its power section supports bidirectional infeed and regeneration, so the unit can handle both line-side power intake and regenerative energy flow within the same hardware. Thermal regulation is provided by internal air cooling with an integrated blower, which keeps airflow moving across the heat sink without external fans. The enclosure has an IP20 rating and must be mounted in a closed-type cabinet to protect it from dust and fluid ingress. The supported continuous output range of 15 to 75 kW covers a broad span of medium-power motor applications, including conveyor systems, general automation axes, and spindle-related duties.

The hardware is identified as Design Version 1, indicating the first mechanical revision of this controller format. The family code HCS03 links the unit to compatible power sections and related accessories, and Voltage code 05 identifies the insulation spacing intended for the 500 V class. These identifiers help keep model selection and system matching consistent across the platform. They also distinguish this unit from similar controllers that use different voltage classes or internal arrangements.
