The Samson locator reports a large feedback error when the actual valve position remains unchanged, usually exceeding 10%. What is the reason?

First, you need to say what model of locator it is

The locator isn’t calibrated; verify it again. If the system is set to automatic mode, then the PID values need to be checked

After the valve is calibrated and has been operating for some time, it is normal for there to be a discrepancy between the set value and the feedback value; in such cases, calibration is required.

Re-calibrate the locator. Could there be a problem with the wiring as well?

It is recommended to calibrate the positioner first, and then determine the stroke deviation
