About the Offset Range Verification Screen
on a grinder, range checking units for this screen are always RADIUS,
regardless of the program/control mode
display format is fixed
Mode Places to the left of the decimal point Places to the right of the decimal point
inch 3 5
metric 4 5
data entry is bounded by the programming resolution of the axes
When Does Verification Occur
Verification occurs when a value enters the table from:
• data entry screens • PAL • paramacros
Important: The control does not perform the verification if the value, old
or new, is zero, nor does it check G10 data-setting codes.
Verify for Maximum Value
This value represents the absolute maximum value per table for all tool
offsets in that table.
If you enter: then:
a positive number greater than the maximum value the control generates the error message:
“OFFSET EXCEEDS MAX VALUE”
a negative number less than the negative of the
maximum value The control does not modify the value in
the table.
Verify for Maximum Change
This change represents the amount an offset may change from its current
value. If you exceed the amount set by the system installer in AMP, the
change is not allowed. The control generates the error message “OFFSET
EXCEEDS MAX CHANGE.”
