Answer
There are two ways to start a positioning operation:
(1) Set the "[Cd.3] Positioning start No.", and turn ON the positioning start signal.
(2) Use the dedicated instructions "ZP.PSTRT1, ZP.PSTRT2, ZP.PSTRT3, ZP.PSTRT4".
[Example of a program which starts axis 1]
Execute [ZP.PSTRT1 "U0" D30 M32]
"U0": Head I/O number
D30: System area
D31: Complete status
D32: Start number
M32: ZP.PSTRT1 instruction complete device
M33: ZP.PSTRT1 instruction error complete device
(Note): With QD77MS16/LD77MS16/LD77MH16, the dedicated instructions are enabled only for 1 to 4 axes.
Note that a positioning for 5 to 16 axes must be started by (1).
