Product Description:
The HCS01.1E-W0054-A-03-A-ET-EC-NN-L3-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. It functions as the power and control interface between a three-phase mains supply and servo or induction motors, converting line power into regulated output that follows commanded motion profiles. This arrangement lets the controller regulate motor speed, torque, and position from a higher-level control system while matching the motor to changing load demands. By integrating power electronics, encoder evaluation, and network communication in one housing, the unit supports compact cabinet layouts for pick-and-place stations, conveyors, and format-adjustable production equipment.
Its supply stage operates on 3 x AC 200 to 500 V with a ±10% tolerance, allowing direct connection to common factory voltages without an external transformer. The current stage can deliver a peak of 54 A, providing headroom for rapid motor acceleration or regenerative braking events. An internal blower moves air through the chassis to remove heat, so cabinet airflow can be directed across the drive without external ducting. Field communication is handled through MultiEthernet, enabling parameter access over multiple industrial Ethernet protocols from the same port. The housing carries an IP20 rating for protected cabinet installation, and the unit is identified as size HCS01, which indicates its frame dimensions and connector positions.
The feedback connector is configured for Encoder IndraDyn Hiperface/EnDat 2.1/2.2, supporting high-resolution position loops without extra interface cards. It also allows the drive to work with compatible motor feedback systems for precise position and velocity control. Functional safety is provided by integrated STO (Safe Torque Off) channels, which remove gate signals to the output stage during emergency stops. The power section supports infeeding and fed operation, so it can supply DC-link energy to neighboring axes and absorb regenerated power from decelerating loads. The drive uses a BASIC control section, which places the motion and interface functions in a replaceable module.
