Product Description:

The HCS01.1E-W0008-A-03-B-ET-EC-EC-SB-NN-FW is a compact drive controller manufactured by Bosch Rexroth Indramat as part of the HCS IndraDrive Controllers series. It functions as the power and control stage for single-axis servo or induction motors in industrial automation cells, converting three-phase supply energy into precisely modulated output for closed-loop motion. By integrating control electronics and power semiconductors into one enclosure, the unit simplifies cabinet layouts and supports coordinated multi-axis operation through standardized fieldbus connectivity.

For power interfacing, the controller accepts 3 x AC 200–500 V ±10%, allowing the same unit to operate in low- and medium-voltage plants. This wide mains range supports use with common industrial three-phase supply systems. Within this input window, it can deliver 8 A peak current, which supports short acceleration bursts for compact synchronous or induction axes. Heat generated by the switching devices is removed through internal air blower cooling, so external ducting is not required. Communication with motion or process controllers runs over MultiEthernet, which can use PROFINET, EtherNet/IP, EtherCAT, or SERCOS. The housing has an IP20 ingress rating, so the controller is intended for installation inside a closed electrical cabinet. The unit is in the HCS01 line and design version 1.

Drive logic is handled by a BASIC control section, which provides the core control configuration for this hardware. The first feedback port supports Encoder IndraDyn Hiperface/EnDat 2.1/2.2 on interface 1, and the second supports Encoder IndraDyn Hiperface/EnDat 2.1/2.2 on interface 2 for matching dual-loop encoder connections. The DC link uses an infeeding and fed power supply unit, which allows multiple controllers in the same group to share regenerative energy. This arrangement supports consistent dual-channel feedback handling while enabling returned energy from decelerating axes to be used within the shared drive group.
