Product Description:
The HCS01.1E-W0028-A-03-A-CC-EC-EM-L3-NN-FW is a drive controller produced by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. It serves as the central power and control element for coordinated motion axes in factory automation, supplying regulated current to synchronous or induction motors while exchanging real-time status data with higher-level PLCs. This arrangement supports precise speed, torque, and position control in automated equipment.
Field communication is handled through a SERCOS III master interface that supports cross-communication between multiple drives. Thermal management is achieved by internal air cooling that moves cabinet air through an integrated blower, eliminating external ductwork. The power stage accepts a three-phase supply of 3 x AC 200 to 500 V ±10%, making the unit usable on worldwide mains without tap changes. Its device peak current rating of 28 A provides short-term torque boosts during acceleration or load shocks, while continuous current is regulated by the control electronics. With an enclosure rating of IP20, the controller is intended for installation inside a closed electrical cabinet where solid-object protection is already provided by the panel.
The control section fitted to this model is the ADVANCED version, which adds extended motion functions and pairs directly with the HCS01 power section through a keyed connector. Feedback from motors can be processed through the Encoder IndraDyn Hiperface/EnDat 2.1/2.2 input, and older systems can be supported through the separate Encoder emulation channel for backward compatibility. Safety is addressed by an integrated STO (Safe Torque Off) interface that removes motor-energizing signals without opening the mains circuit, allowing rapid compliance with EN ISO 13849-1 safety stops. The power module can operate in either infeeding or fed-axis mode, depending on the internal power supply arrangement.
