In automated robotic welding, which consequence results when PLC cycle time exceeds encoder feedback rate?

💡 Explanation

Positional accuracy degrades because the PLC's decision-making lags behind the actual joint positions reported via the encoder; this involves the *control loop delay* mechanism. Therefore, the robot becomes inaccurate rather than problems with welding parameters arising from arc instability.
