Set Data
Processing contents
(1) The S.FG instruction performs the following operation.
Condition
E1  X1
< E1  X
X (i = 2 to n)
i-1 i
Xn < E1
(2) When n = 0 there is no processing.
(3) When X > X , the value is cut off to n = i-1 (Data after that is ignored.)
i-1 i
When there are multiple Y
Operation Error
In the following cases, the error flag (SM0) turns ON and the error code is stored in SD0.
Error code
When an operation error occurs
When the values of
