10 ADVANCED POSITIONING CONTROL
10.3 Setting the start block data
10.3.1 Relation between various controls and start block data
The "start block data" must be set to carry out "advanced positioning control". The
setting requirements and details of each "start block data" item to be set differ
according to the "
Da.12 Special start command" setting.
The following shows the "start block data" setting items corresponding to various
control methods. The operation details of each control type are explained starting in
section 10.3.2. Also refer to section "10.4 Setting the condition data" for details on
"condition data" with which control execution is judged.
(The "start block data" settings in this chapter are assumed to be carried out using the
AD75 software package.)

: One of the two setting items must be set.
: Set when required (Set to " – " when not used.)
: Setting not possible
–
: Setting not required (Setting value will be ignored. Use the initial value or a value within the setting range.)
* The "NEXT start" command is used in combination with "repeated start (FOR loop)" and "repeated start (FOR
condition)". Control using only the "NEXT start" will not be carried out.
REMARK
It is recommended that the "start block data" be set whenever possible with the
AD75 software package. Execution by sequence program uses many sequence
programs and devices. The execution becomes complicated, and the scan times will
increase.
