What is the difference between "RotMonOn" and "ShowEncPos" in Lexium SD328 drives

For Lexium SD328 stepper drives range,

When CTRLS_MotEnc = "ShowEncPos" is meant to have motor encoder connected. Stepper drive will show the position of motor encoder. But Rotation Monitoring will remain De-activated. This means "Flt_pDiff" ( Difference between Reference position and Actual position) will not be monitored. Fault A320 - tracking error too high is not detected
