1 Spot Welding Application Using a Motor Gun
1.12 Tip Wear Detection and Wear Compensation (Motor Gun)
5. WEAR (F)
Present wear amount at the fixed side tip is indicated.
The value is updated when the wear detection is finished.
Also, the universal output signal specified at {SETTING (OUT#)} is
turned ON when the value in {CURRENT} has exceeded the value in
{TOLERANCE}.
6. RESET WEAR (M)
The value at {RESET WEAR (M)} can be cleared when the signal spec-
ified to {RESET WEAR (M)} is turned ON.
7. RESET WEAR (F)
The value at {RESET WEAR (F)} can be cleared when the signal speci-
fied to {RESET WEAR (F)} is turned ON.
8. TIP MOUNTING ERROR (M)
Movable side tip mounting error is indicated.
The value is updated when the tip mounting error detection is finished.
For the details, refer to chapter 1.12.8
Detection".
9. TIP MOUNTING ERROR (F)
Fixed side tip mounting error is indicated.
The value is updated when the tip mounting error detection is finished.
For the details, refer to chapter 1.12.8 .
10. BASE POS (M)
In case {BASE POS (M)} has not been register, the detected position is
registered as the base position by the execution of the movable side tip
detection motion.
11. BASE BOS (F)
In case {BASE POS (F)} has not been register, the detected position is
registered as the base position by the execution of the dry spot touch
motion.
12. DETECTED THICKNESS (CURRENT, SETTING(M))
Detected thickness of the workpiece is indicated to this item when the
workpiece thickness detecting function is used.
If a value more than 0 is set to {SETTING (M)}, the detected thickness is
written to the specified register.
For the details, refer to chapter 1.13.8
tion Function".
13. TOUCH SPEED
Set the gun closing speed with a link speed (%) when executing a wear
detecting dry spot motion (executing SVGUNCL using PRESSTWC
tag).
14. DETECT PRESSURE
Set the detecting pressure for the touch detection when executing the
wear detecting dry spot motion (executing SVGUNCL using
PRESSTWC tag).
15. WEAR RATIO (FIXED SIDE)
To the wear amount detected by the wear detection operation (TWC-C),
specify the wear ratio to the fixed side tip.
16. WEAR COMPENSATION OFFSET (FIXED SIDE)
If the fixed side tip is required to be always shifted for a certain amount,
set the certain shifting amount to this item.
17. WEAR DETECT SENSOR DIN NO.
Set a direct-in No. to which a sensor signal used for the movable side tip
detecting motion (wear detecting operation (TWC=B)) is input.
