Which consequence results when a PLC controlling a robotic arm's inverse kinematics experiences an integer overflow with coordinated motion?

A)Joint trajectory follows unexpected arc
B)Motor overheating due torque increase
C)Halting the emergency stop procedure
D)Communication error and program freeze

💡 Explanation

An integer overflow in the PLC's kinematic calculations causes unexpected positions, so the Inverse Kinematics mechanism miscalculates joint angles. Therefore, the robotic arm follows an unexpected trajectory from the intended path, rather than other electrical or communication failures.
