*1 The data of the item(s) where the values within the recommended range are given in the parentheses are stored by the
system. Users cannot set the data.
*2 When control is to be started from the initial status, the data must be cleared with the sequence program.
(2) Execution cycle ( T)
Set the execution cycle in SD1500 and SD1501 as real numbers.
