parameters are excluded from the check sum.
(1) Setting parameters
(2) Parameters shown in the following table (Parameters excluded
from the check sum).
(3) Parameters specified by parameter No. 13731 to 13750
(4) Parameters specified by parameter No. 13751 to 13770
Parameters excluded from the check sum(M series)
