← TechnologyWhich outcome occurs when a PLC-controlled robotic arm exceeds its programmed acceleration limits with malfunctioning inertial measurement unit sensors?
A)Encoder drift causes position inaccuracy✓
B)Thermal runaway damages servo motors
C)Kinematic singularity locks joint motion
D)PID feedback oscillations exhaust energy
💡 Explanation
Encoder drift causes position inaccuracy because the inertial measurement unit sensors fail to provide accurate acceleration feedback, misrepresenting joint positions; therefore, the arm trajectory diverges because the controller relies on faulty sensor data, rather than limiting acceleration.
