PSTRT3: Axis 3

PSTRT4: Axis 4

(2)The block start, OPR start, current value changing, and multiple axes simultaneous start can be carried out by the setting of "start number" 7000 to 7004/9001 to 9004 in ((S)+2).

(3)The PSTRT instruction completion can be confirmed using the complete devices ((D)+0) and ((D)+1).

(a) Complete device ((D)+0)

This device is turned ON by the END processing of the scan for which PSTRT instruction is completed, and turned OFF by the next END processing.

(b) Complete state display device ((D)+1)
