Product Description:

The HCS01.1E-W0028-A-03-B-ET-EC-NN-L3-NN-NW is a drive controller from Bosch Rexroth Indramat’s HCS IndraDrive Controllers series. Designed for cabinet installation, the unit coordinates torque and speed in servo axes and induction motors used in packaging, printing, and material-handling cells. By combining power electronics and integrated safety, the controller replaces discrete starters and relays while providing networked motion control. The part number identifies this version within the HCS01 line.

The power section accepts a three-phase supply of 3 x AC 200...500 V ±10%, so the same hardware can be wired to both 230 V and 480 V plant buses without tap changes. During acceleration, the inverter can deliver up to 28 A of peak current, allowing short-term torque surges before it returns to continuous limits. Thermal energy is removed by internal air cooling through an integrated blower, eliminating external ductwork and keeping the panel rating at IP20 for use in closed electrical enclosures. Drive-to-host communication takes place through MultiEthernet, enabling real-time exchange over EtherNet/IP, PROFINET, SERCOS over Ethernet, or standard TCP/IP networks.

The attached control section is classified as BASIC, reflecting a pared-down I/O set that is sufficient when higher-level PLCs handle sequencing. The integrated safety channel provides STO, so motor torque is reliably suppressed when the function is invoked. Position feedback is wired to a universal encoder interface for IndraDyn Hiperface and EnDat 2.1/2.2 signals, which simplifies integration across different motor families. Power is routed through the shared DC link in an infeeding and fed configuration, allowing the device to either supply or absorb regenerated energy depending on the arrangement. This hardware is design version 1, includes no optional second interface, and carries no extra extensions.
