*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) Execution cycle ( T)
Set the execution cycle in SD1500 and SD1501 as real numbers.

Processing contents
(1) The S.SUM instruction performs the following processing.
e1 E1
0 ––
E1  ILC
1
E1 > ILC
(2) The T value used for the operation changes depending on the input range (RANGE) setting.
• When RANGE = 1, T = 1
• When RANGE = 2, T = 60
• When RANGE = 3, T = 3600
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
4100
non-normalized number
When the RANGE setting is other than 1 to 3
When the values of
4140
non-normalized number
4141 When an operation error occurs
