*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 The loop tag memory and loop tag past value memory occupy a total of 128 words. (Refer to Page 27, Section 3.3.1 for
details.)
(2) Execution cycle ( T)
Set the execution cycle in SD1500 and SD1501 as real numbers.
Set Data
Processing contents
(1) Either of the following processings is performed depending on the mode select signal (e1) setting of the input data.
(a) In the manual mode (e1 = 0), the output value (BW), initial deviation value (Xg) and deviation (Xp) are calculated
with the following expressions.
• BW = output control value (E2)
• Xq = output control value (E2) - output set value (E1)
• Xp = output control value (E2) - output set value (E1)
(b) In the automatic mode (e1 = 1), the output value is calculated with the following expression.
