DSMB127: Product OverviewThe DSMB127 is an axis computer module that functions as the central motion control processor for ABB’s S4C+ robot controller system. This critical component is installed in the main computer rack and is responsible for all real-time robot motion calculations, including trajectory planning, inverse kinematics, and servo motor control. The module receives movement commands from the main computer board and translates them into precise control signals for the drive modules that power the robot’s servo motors.As the core of the robot’s motion control system, the DSMB127 performs complex mathematical calculations to determine the optimal path between programmed points while maintaining specified velocities, accelerations, and positional accuracy. It continuously monitors feedback from resolvers or encoders on each robot axis, implementing closed-loop control to ensure the actual robot movement matches the programmed path. The module also handles advanced motion features such as path accuracy optimization, collision detection, and coordinated external axis movement.
