Product Description:

The HCS01.1E-W0028-A-03-B-ET-EC-NN-NN-NN-FW is a drive controller from Bosch Rexroth Indramat's HCS IndraDrive Controllers series. As a compact component in multi-axis automation, it converts three-phase supply power into regulated output for synchronized servo and induction motors, enabling coordinated motion tasks such as positioning, speed control, and torque regulation on production machinery. The unit belongs to the HCS01 line, making it suitable for low- to mid-power axes where cabinet space and modular integration are important.

The controller accepts a three-phase mains range of 3 x AC 200-500 V ±10%, allowing it to operate on common 230 V or 400 V factory networks without hardware changes. The unit is design version 1, which corresponds to the first mechanical release of the HCS01 platform. Peak output capability reaches 28 A, which is the highest motor phase current the power stage can supply during acceleration or other transient load conditions. Heat produced by the IGBTs is removed through internal air cooling with an integrated blower, eliminating the need for cabinet ducting. Communication with higher-level PLCs is established through MultiEthernet, giving compatibility with EtherNet/IP, PROFINET, and EtherCAT protocols.

The control section is the BASIC variant, matching note B in the type code, and it provides standard positioning functions without integrated safety logic. Feedback wiring connects to the motor through a combined encoder socket that supports Encoder IndraDyn Hiperface/EnDat 2.1/2.2, enabling high-resolution position data for the control loops. The assembly carries an IP20 rating, which provides finger-safe terminals but no protection against liquids. The DC bus supply type is Infeeding / Feeded, meaning energy is provided by an external line module so shared bus configurations and regenerative operation can be used. The secondary fieldbus slot, safety interface, and second encoder channel are not populated.
