Which outcome occurs when increased hysteresis affects quadrature encoder signals fed to a PLC in a high-precision servo-controlled robotic arm?

💡 Explanation

Spurious positional errors accumulate in the PLC because increased hysteresis in the quadrature encoder distorts the pulse width modulation signals during high-speed arm movements. This introduces integrated error rather than correcting kinematics or frequency response, therefore leading to positional drift.
