Product Description:
The HCS01.1E-W0028-A-03-B-ET-EC-NN-S4-NN-PW is a drive controller manufactured by Bosch Rexroth Indramat. It belongs to the HCS IndraDrive Controllers series. It serves as the power and command interface between a three-phase mains supply and servo or induction motors, enabling acceleration, speed regulation, and controlled braking in automated equipment such as packaging lines, pick-and-place axes, and assembly stations. In operation, it converts incoming electrical power into regulated output for the motor so the connected axis can follow commanded motion with stable response. This supports automated systems that require repeatable starts, stops, and speed changes during continuous production cycles.
Inside the housing, the controller accepts a three-phase supply of 3 × AC 200…500 V ±10%, permitting operation on both 220 V and 480 V plant networks. An integrated blower provides internal air cooling and maintains thermal stability when the unit delivers the maximum 28 A device peak current during rapid load changes. Motion data transfers over the MultiEthernet port, allowing PROFINET, EtherNet/IP, or EtherCAT connectivity through the same interface. Position feedback returns through the socket that supports IndraDyn Hiperface/EnDat 2.1/2.2 encoder feedback. A second feedback channel is not equipped, so the controller remains focused on a single primary motor feedback connection.
The control section supplied with the device carries the BASIC designation, which keeps the parameter set suited to general-purpose servo and spindle axes. The power stage uses infeeding and regenerative feedback, allowing braking energy to return to the DC bus instead of being dissipated as heat. Returning braking energy to the DC bus can help reduce heat buildup inside the enclosure during deceleration cycles. Within the compact HCS01 frame, the mechanical footprint matches earlier units to simplify cabinet layouts. The controller has an IP20 ingress rating, so it must be installed inside a closed electrical enclosure away from conductive dust or moisture.
