Offset Tables and Setup

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.”

Use this feature to allow the manual activation of tool offsets without the
need to program a D-- or H--word to call the corresponding offset number.
This may be necessary when a broken tool has been replaced using the Jog
Retract feature, or if a program is to start execution with a tool active in the
chuck and no tool offsets programmed, etc.

Important: The control must be in either cycle stop or E-Stop states
before an attempt is made to change the active offset using this method.

The axis that is selected as the length axis (the axis that length offsets are
applied to) is shown in reverse video. The length axis is selected in AMP
or through programming as discussed on page 20-9.

If it is necessary to change the current tool offset values or to activate tool
offset numbers without programming an H-- or D--word, follow these steps:
