[Da.13] Special start instruction
Set Special start instruction for performing Advanced positioning control. (Set the method by which the positioning data set in
[Da.12] Start data No. will be started.)
The setting value for this area is stored in the same buffer memory address as that of [Da.14] Parameter. Set this area
according to the buffer memory configuration.
For details on the control, refer to the following.

Default value
The default value is 0: Block start for all the axes.
Special start instruction Setting
value Description
Block start 0H With one start, executes positioning data in a block in the set order.
Condition start 1H Performs the condition judgment specified in Condition data for the specified positioning data. If the
conditions have been established, Block start data is executed. If the conditions have not been
established, that Block start data is ignored, and Block start data of the next point will be executed.
Wait start 2H Performs the condition judgment specified in Condition data for the specified positioning data. If the
conditions have been established, Block start data is executed. If the conditions have not been
established, the control stops (waits) until the conditions are established.
Simultaneous start 3H Simultaneously executes the positioning data having the number for the axis specified with Condition
data (Outputs pulses at the same timing). Up to four axes can start simultaneously.
Repeated start (FOR loop) 4H Repeats the program from the block start data set with FOR loop to the block start data set in NEXT for
the specified number of times.
Repeated start (FOR condition) 5H Repeats the program from the block start data set with FOR condition to the block start data set in NEXT
until the conditions set in Condition data are established.
NEXT start 6H Set the end of the repetition when 04H: Repeated start (FOR loop) or 05H: Repetition start (FOR
condition) is set.
