This means the tip dresser is sensing an earlier torque increase than expected.
Assuming you checked the path, position, and gun zero position. Confirm you have the right thickness value set.
If everything else is good then adjust $sgtdset(x) $cnt_thrsh to a higher number. This is the distance above thickness value when contact is sensed before sending alarm.

If path and point are good how much can that value be increased to? Originally began at a value of 10. also is there any other suggestion for this fault

You can keep increasing that value. but normally something else is causing your issue. I have never gone above 20. Reference $sgtdset.$cntct_tpdst or look for TDSumlog.dg in your MD backup files or from the error diagnostic files in robot homepage. Look at Tipcntc_dist. This is the distance of the servogun tips when the system thinks contact was made with the dresser.
while in tdsumlog look at free_torque. If that is varied more than a multiple of 2.5 adjust $Sgtdset.$cntct_fctor. To a more appropriate multiple do not go crazy on this var though.
