Product Brief:

KRC4 is the fourth‑generation robot controller developed by KUKA,covering compact,smallsize‑2,standard,midsize and extended cabinet variants to match different robot payload and axis expansion requirements. It adopts multi‑core industrial PC plus CCU central control unit architecture,runs KSS robot system software with SSD solid‑state storage for faster system startup and higher data reliability. Integrated safety PLC realizes SIL3‑level safety logic processing,greatly improving system operation safety performance. Cooperate with smartPAD / smartPAD‑2 teach pendant to complete robot manual jogging,KRL program editing,RSI real‑time sensor coupling,parameter configuration and comprehensive fault diagnosis. Rich industrial bus interfaces support seamless connection with peripheral automation equipment,widely used in welding,handling,palletizing,assembly,machine tending and other automated production stations. This is mainstream robot spare component,used for system maintenance and module replacement of existing KRC4 robot systems. Please confirm robot mechanical model,cabinet variant,KSS software version and hardware revision before purchasing.
