Product Description:

The HCS01.1E-W0028-A-03-B-ET-EC-NN-L3-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. Within an automation cell, it converts three-phase mains power into regulated output for synchronous or asynchronous motors while exchanging motion commands with a PLC. The unit belongs to the compact HCS01 line, giving machine builders a small-footprint module that manages torque and speed loops for individual axes in packaging, material-handling, and process equipment. It functions as both a rectifier and an inverter, permitting controlled acceleration, deceleration, and safe shutdown in one device. This integrated arrangement supports compact cabinet layouts where one controller is assigned to one motorized axis.

For wiring, the controller accepts a three-phase supply of 3 x AC 200–500 V ±10%, which reduces the need for different voltage-specific variants. Internally, heat is removed by internal air cooling through an integrated blower, so no external fan tray is required. During dynamic acceleration, it can deliver a device peak current of 28 A, giving the control loop headroom to overcome motor inertia or load shocks. That current reserve helps the drive maintain commanded motion during short acceleration demands and changing mechanical loads. Networked motion data pass through the MultiEthernet port, and one connector supports PROFINET, EtherNet/IP, and EtherCAT for flexible network integration. Protection is limited to IP20, so the unit must be mounted inside a closed electrical cabinet.

Axis feedback is handled through an encoder socket for Encoder IndraDyn Hiperface/EnDat 2.1/2.2 signals, allowing automatic motor identification. This lets the controller exchange position data with compatible motor feedback systems used on Rexroth servo platforms. The control section is the BASIC variant in Design Version 1, and the power section uses the HCS01 DC-bus topology of Infeeding / Feeded. Functional safety is provided through the STO (Safe Torque Off) input, which disables torque without interrupting mains wiring. That safety function allows torque to be removed quickly while the main supply connections remain in place.
