Product Description:
The HCS01.1E-W0028-A-03-B-ET-EC-EM-L4-NN-FW is a modular drive controller designed by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. The unit functions as the power and control interface between a three-phase supply and connected servo or induction motors, executing torque and speed commands from a higher-level motion system. By combining control electronics, safety circuits, and power conversion in one housing, it simplifies axis integration in packaging, handling, and assembly equipment. It can be used in machines that require both precise positioning and stable speed control, including feeders, indexing stations, and transfer systems.
Its communication backplane is equipped with a MultiEthernet interface, allowing direct connection to EtherNet/IP, PROFINET, or EtherCAT networks without additional hardware. The power section accepts up to 3 x AC 200…500 V ±10%, covering common global mains levels and supporting use on different plant supplies. During acceleration, the device can deliver a peak phase current of 28 A, providing short-term torque headroom for high-inertia loads. Thermal energy is removed by internal air cooling through an integrated blower, so separate cabinet ducting is not required. The housing carries an IP20 protection rating, which means it is intended for installation inside a control cabinet where finger-safe protection is sufficient.
The controller uses the BASIC control section and is supplied in design version 1. Feedback connectivity is handled by an IndraDyn Hiperface/EnDat 2.1/2.2 encoder interface for absolute position devices, while a dedicated channel provides encoder emulation signals for legacy drives or PLC counters. That arrangement allows the unit to support newer feedback hardware while still interfacing with systems that rely on simulated encoder signals. For fail-safe operation, integrated STO (Safe Torque Off) and SBC (Safe Brake Control) circuits remove motor torque and control the brake as required by the safety PLC. Power is supplied through an infeeding and fed supply section, allowing the unit to share or return DC bus energy with other axes in the same drive group.
