■Block memory
■Operation constant
■Local work memory
The system uses this area as a work area.
To start the control from the initial status, clear data by using a sequence program.
■Execution cycle (T)
Set the execution cycle (T) in SD816 and SD817 in single-precision real number.
Processing details
This instruction sets the lag time (T
1
) of (s2) and the lead time (T
2
) and performs lead-lag compensation according to the
actuating signal (e1).
