Product Description:

The HCS01.1E-W0003-A-02-E-S3-EC-EP-L3-NN-FW is a compact drive controller from Bosch Rexroth Indramat and belongs to the HCS IndraDrive Controllers series. In an automation cell, it acts as the closed-loop link between the motion control system and servo motors, modulating current and voltage so that axes follow commanded profiles with consistent accuracy. By integrating power electronics, safety logic, and fieldbus connectivity, the unit helps simplify cabinet layouts in packaging, printing, and material-handling lines that require coordinated multi-axis motion. Its compact format suits installations where precise servo control is needed without using a larger drive platform.

The controller accepts a three-phase supply of 3 x AC 110...230 V ±10% and converts it into regulated DC for the inverter stage. The inverter can deliver up to 3 A of peak output current, which suits low-power servo axes such as small conveyors or index tables. Thermal energy produced by the switching devices is removed by internal air cooling through an integrated blower, eliminating the need for external ducting and keeping installation simple. Command data and real-time synchronization are handled over SERCOS III, allowing very fast cyclic communication when the unit is integrated into compatible motion systems. For personnel protection, the hardware provides STO (Safe Torque Off), which disables motor energization without cutting mains power during emergency stops or service work.

The housing carries an IP20 rating, so the unit is intended for mounting inside control cabinets where touch-safe but unsealed equipment is acceptable. The control section in this build is the ECONOMY variant, which provides core motion functions with a reduced feature set. Motor feedback is processed through a universal encoder port that supports IndraDyn Hiperface and EnDat 2.1/2.2 encoders, making it suitable for systems that use different feedback technologies. Power flow follows an infeeding and feeding topology, allowing the device to share a common DC bus with other axes for energy exchange during braking and acceleration.
