Which position error increases when a PLC executing inverse kinematics operates with insufficient encoder resolution on robotic arm joints?

💡 Explanation

Lacking granular encoder feedback, the PLC’s inverse kinematics uses a discrete approximation, a form of quantization error. Therefore, with each interpolated move command to a joint, there's amplified inaccuracy in the end-effector’s final position, rather than issues directly affecting motor torque or sensor range, because resolution fundamentally limits precision.
