Which outcome primarily results when thermal expansion misaligns the encoder disk within a high-speed robotic servo?

💡 Explanation

In robotic servos, thermal expansion causes **encoder** misalignment, triggering the **vernier effect**. Because the encoder's output becomes inaccurate, the closed-loop control system misinterprets position; therefore, there is increased positioning error rather than improved damping, because torque response degrades unevenly.
