Product Description:
The HCS01.1E-W0028-A-03-A-CC-EC-PB-NN-NN-FW is a drive controller from Bosch Rexroth Indramat in the HCS IndraDrive Controllers series. It converts three-phase supply energy into regulated DC bus power and issues precise torque, speed, and position commands, linking electric servomotors to supervisory control systems in automated machinery. This role allows the controller to coordinate motor response with changing motion commands during synchronized machine operation.
In operation, the controller exchanges real-time motion data over the SERCOS III master interface, allowing cross-communication with other axes. Its cooling relies on an internal blower, so additional cabinet airflow is not required for heat removal at the drive itself. The blower directs heat across the heat sink fins, helping maintain semiconductor temperatures during full-load cycles. The power stage accepts three-phase mains from 3 x AC 200...500 V ±10%, making it compatible with common factory supply networks. During dynamic acceleration, the device can deliver up to 28 A of peak current to the connected motor, supporting short bursts of torque without triggering overcurrent faults.
The control section fitted to this housing is classified as ADVANCED, which supports extended drive-based functions such as electronic gearing and integrated technology packages. The housing has IP20 protection, so the unit must be installed inside a closed electrical cabinet. Feedback wiring connects through a universal encoder port that reads Hiperface/EnDat 2.1/2.2, allowing use of high-resolution IndraDyn sensors. A separate fieldbus plug provides PROFIBUS for plant-level I/O mapping. The power supply concept uses infeeding and DC-bus-fed operation, enabling the drive to share regenerated energy with other modules on the DC bus. There is no dedicated safety interface, so emergency stop and safe torque off must be handled externally.
