clamp output signal is sent, and before the weld complete signal is received.
⇒
Return the system to normal operation and re-execute weld.

ERROR CODE E5028 Cannot achieve set force.
The gun does not obtain the set closing pressure within 5 seconds after the gun starts
closing.
Main causes include:
1. Tip wear measurement is not executed.
2. Incorrect taught point (closing pressure is not defined for the recorded position).
3. Closing pressure is set too high.
4. Workpiece is too thin.
5. Incorrect lower limit motion setting (LLIMIT command).
⇒
Perform the tip wear measurement.
⇒
Reteach the point.
⇒
Decrease the closing pressure.
⇒
Ensure the workpiece specifications are correct and the workpiece is in the correct
position.

ERROR CODE E5029 Gun tip stuck.
Indicates that the tips are stuck. More power is required to open the gun, following a
weld, than the stuck detection value, set in AUX 1021 Force for Stuck Detection [kgf].
If the stuck detection value is set below the power level required for normal operation,
the gun cannot operate properly and the error is set.
⇒
If the gun is stuck, release it manually.
⇒
If the gun is not stuck, verify that the stuck detection value (AUX 1021, Force for
Stuck Detection [kgf] ) is set correctly. This setting may need to be increased.
