Product Description:

The HCS01.1E-W0028-A-03-B-ET-EC-EC-S4-NN-FW is a compact HCS drive controller produced by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. The unit supplies regulated power and closed-loop control signals to a connected motor, forming a drive axis in an automated machine. By accepting three-phase mains input and exchanging data with a plant network, it carries out speed, torque, and position commands from a higher-level motion control system. This arrangement allows the controller to match motor response to changing process demands during positioning, speed regulation, and torque-controlled movement.

For network integration, the controller provides a MultiEthernet interface that supports common industrial protocols, and this single port allows communication with PLCs and diagnostic tools. Its control section uses the BASIC design, so application functions and parameter memory remain on the main board without optional expansion cards. The power stage accepts 3 x AC 200–500 V mains with a tolerance of ±10%, and the integrated converter can deliver a peak output of 28 A during short acceleration periods. The housing is rated IP20, which helps protect against accidental contact with live parts, and cooling is provided by a built-in air blower that circulates internal air without requiring external ducting in most cabinet layouts.

In this product line, the device is design version 1, indicating the first version of this housing and power section. It uses two encoder channels for IndraDyn Hiperface and EnDat 2.1 / 2.2 feedback, so precise rotor position information is available for closed-loop operation and for connection to compatible motor feedback systems. The power supply is configured for infeeding and fed operation, which allows the drive to receive DC-bus energy from an upstream supply or return regenerated power to the common line. This operating mode suits multi-axis systems that share power across several connected drives.
