Which disruption occurs with excessive PLC scan time?

💡 Explanation

Increased PLC program execution (scan) time leads to missed encoder pulses and timing inaccuracies in control loops; this results in under-damped robotic arm movements via the computed inverse kinematics because positional corrections update irregularly at extended period intervals, therefore oscillations occur rather than precise, smooth motions.
