3. WEAR DETECT METHOD
Set the method of wear detection.
Select from the two methods below.
RIN: Operates the wear detection by using a sensor.
TOUCH: Operates the wear detection by performing the board touch.
4. WEAR VALUE CALCULATE METHOD
Set the calculate method of the wear value when operating the wear
detection by using the TWC-C.
Select from the two conditions below.
TOTAL VALUE :Multiplying the current detected total value of the wear
(fixed side wear value + movable side wear value)
by the value of the "WEAR RATIO (FIXED SIDE)"
in the SPOT SUPERVISION window makes the
fixed side wear value, and the rest of the wear value
becomes the movable side wear value.
ADD :Multiplying the wear difference between the current and
the last detected total value of the wear by the value of
the "WEAR RATIO (FIXED SIDE)" in the SPOT
SUPERVISION window, and adding the product
above and the last fixed side wear makes the fixed
side wear value. Also, the addition of the rest of the
wear difference and the last movable side wear value
becomes the movable side wear value.
5. ORDER OF WEAR DETECT INSTRUCTION
Set the order of the wear detect instruction.
Select from the two conditions below.
TWC-A → TWC-B : Calculates the wear value only when TWC-A is
executed first (dry spotting touch motion), and
then TWC-B (movable side tip detection motion)
is executed next.
NO LIMIT: There is no order to execute the instructions.
6. WEAR COMPENSATE TEACH METHOD
Set the confirmation method when teaching the positions under the con-
dition that the tip is worn out.
Select from the three conditions below.
MESSAGE: Displays the message "Compensated position"
after teaching the positions.
CONFIRM+MSG:The confirmation dialog "Compensate?" appears
when teaching operation.
If pressing "YES", the positions will be registered.
After the registration, the message "Compensated
position" appears.
NOT CONFIRM: The confirmation dialog and the message do not
appear on the screen when teaching the positions.
