Which control error increases when a PLC handling a robotic arm's joint trajectory calculation for welding utilizes insufficient digital filtering?

💡 Explanation

Inaccurate seam weld deposition occurs when insufficient digital filtering in the PLC leads to noisy data, because this degrades `inverse kinematics` calculation accuracy, impacting the arm's trajectory. Therefore, positioning errors accumulate, rather than causing motor inefficiencies or simple overshoot with correct filtering hardware.
