4.4 Blade Wear Detection (When Blade Wear Setup is On)

This function calculates the total cutting distance of the cutter blade to indicate when it requires replacement.
This should be used purely as a guide, as the actual cutter-blade wear will vary depending on the material
cut and the cutting conditions (e.g., force) used.
The pen setting areas are grouped together, and the total distances are calculated for each group. Eight
groups can be managed, and they initially correspond to the pen setting areas, so that group 1 corresponds
to setting area 1, group 2 corresponds to setting area 2, and so on. If two or more setting areas are
combined in a single group, the total calculated distance for that group will be the sum of the individual area
values.
It is also possible to include weighting factors for each setting area to correspond to the different wear rates
for different materials and cutting conditions. For example, if setting areas 1, 2, and 3 are combined into one
group with respective total distances of A, B, and C, and the respective factors are 0.7, 1.2, and 1.0, the total
distance for this group will be A x 0.7 + B x 1.2 + C x 1.0.
Wear detection can be switched on or off using the special function settings (see "Enabling/Disabling Wear
Detection" on page 5-3). When disabled, it is not displayed on the PAUSE menu.
If the power is turned off while cutting is in progress, the cutting distance for that operation is not included in
wear-detection calculations.

This indication should be used as a guide for cutter-blade replacement.
This display reverts to the normal READY-mode display when the
key is pressed, but it will reappear when the power is turned on again or if a
setting area is selected again for a group with a wear rate exceeding 100%.
Always zero the total distance display after replacing a cutter blade (see "Clearing
the Total Distance (Wear Rate)"). The display above will disappear, and the
distance calculation will restart from zero.
