ERROR CODE E6540 Beyond AVC tracking ability.
Occurs when the current tracking value exceeds the threshold value and the number of
times value set for RTPM tracking ability errors.
Main causes include:
1. Weld start-point is too far from the groove.
2. Defective weld controller/timer, or weld controller/timer set OFF.
3. The deviation error detection value is set too low.
⇒
Ensure the welding start point is taught in the grove. Starting outside the grove
causes this error
.
⇒
Execute a weld with AVC disabled, to ensure the weld controller/timer is operating
properly.
⇒
If the welding groove is being tracked normally, the deviation error detection value
may be set too low. Increase the value.

2. Defective harness or harness connections.
⇒
Execute a weld with AVC disabled to ensure the weld controller/timer is operating
properly.
