F Series Controller
The F Series Controller is Kawasaki Robotics' (Kawasaki Heavy Industries) family of industrial robot controllers. These controllers act as the control unit for industrial robots — responsible for motion control, program execution and oversight of the robot system's safety.
The F series builds on Kawasaki's mature motion-control and functional-safety technologies, used across the maker's broad portfolio of industrial robots (including assembly, welding, palletizing and machine-tending applications).
The F Series Controller S-type variant is built on the F series; it inherits the functional-safety technologies and extends them with extensive cybersecurity features (including authentication, packet filtering, secure boot, a security log and secure updates) in accordance with the IEC 62443-4-1 standard.
