Caution
(1) The position data for extension motion control board axis shares the user data-hold memory in the
main CPU board as the data saving areas, with the position data for RC axes of the RC gateway
function. For this reason, if the RC gateway function (method of using position data within X-SEL) is
used, some restrictions apply to the number of position data points that can be used.
(2) If you use the position data for RC axes with the RC gateway function, back up the position data for
RC axes before changing the parameters above. The position data of the RC gateway function is
cleared when the parameters above are changed. Initialize the memory and reset the software and
then transfer the saved backup data to the controller, write to FROM, and reset the software.
(3) Under normal circumstances, set the same values for I/O parameters No. 530 and No. 532. The
number of set points of I/O parameter No. 530 becomes valid within the data area defined on the
UBM with I/O parameters No. 531 and No. 532. If the value set for I/O parameter No. 530 is smaller
than the value set for I/O parameter No. 532, the 6A1 error does not occur; such setting should be
used when you want to change the number of data points to be used temporarily for debugging
purpose, etc.
