The R911379381 (HCS01.1E-W0028-A-03-B-ET-EC-NN-L3-NN-NW) HCS01.1E series drive controller from Bosch Rexroth is intended for operation with a central power supply and supports DC bus coupling via the X77 interface, allowing coupling of up to eight similar controllers. It provides motor holding brake control and is compatible with MSM, MCL, MSK, and MS2N motor series. The controller includes a power section, a BASIC type control section, and a HAS09 mounting and connection kit. Communication is handled through a MultiEthernet interface, while encoder feedback is supported via IndraDyn Hiperface/EnDat 2.1/2.2. Protective features include an IP20 rating and Safe Torque Off (STO) functionality. The device operates with a three-phase AC input voltage of 200 to 500 V (±10%), delivers a peak current of up to 28 A, and uses internal air cooling through an integrated blower. The unit requires appropriate programming before commissioning and does not feature an integrated control panel or firmware.
