Your system installer can also write PAL to automatically select and
activate a wheel length and radius/orientation offset number. See your
system installer’s documentation and the PAL reference manual for details.

From Table 13.A, you can see that you cannot program a T word without
inadvertently programming both a length offset and a radius/orientation
offset. By not programming one of the offsets, the control assumes an
offset of 00 is programmed and cancels any active offset value. We
recommend that you always program a T word followed by all 4 digits.
This is to make sure that you are not inadvertently canceling one offset
while trying to activate another.

Your system installer determines in AMP if the control cancels all wheel
length or radius/orientation offsets when you reset the control or when you
execute an M02, M30, or M99 end of program block.
