← TechnologyWhich consequence results when a PLC controlling a robotic arm for welding experiences address bus corruption during positional calculations?
A)Unpredictable arm trajectory results✓
B)Reduced arc welding current occurs
C)Increased deposition feed rate occurs
D)Spatter formation is linearly minimized
💡 Explanation
Unpredictable movements arise because corrupted memory address within the PLC changes targeted joint positions, thus altering trajectory via inverse kinematics. Therefore, the path deviates, rather than affecting welding parameters since servo control loops get false references.
