10 HIGH-LEVEL POSITIONING CONTROL
10.3.2 Block start (normal start)
In a "block start (normal start)", the positioning data groups of a block are continuously
executed in a set sequence starting from the positioning data set in "
Da.12
Start data
No." by one start.
Section [2] shows a control example where the " block start data" and "positioning
data" are set as shown in section [1].
