Users cannot set the data.
*2: The loop tag memory and loop tag past value memory occupy a total of 128 words. (Refer to Section 3.3.1 for details.)
(2) Execution cycle ( T)
Set the execution cycle in SD1500 and SD1501 as real numbers.
Processing contents
(1) Mode judgment
Either of the following processings is performed depending on the operation mode (MODE).
(a) When the operation mode (MODE) is any of MAN, CMB, CMV and LCM
1) The manipulated value (MV) is used as the output value (BW).
2) "(2) Output conversion processing" is performed.
(b) When the operation mode (MODE) is any of AUT, CAB, CAS, CCB, CSV, LCA and LCC,
BW retains the last value.
(2) Output conversion
In the output conversion, the output value is calculated from the following formula.
