Precautions
(1) When positioning is started by the PSTRT
instruction, the positioning start
signals (Y10 to Y13) will not turn ON.
To confirm that positioning control is being executed, use the PSTRT
start
command or the positioning start complete signals (X10 to X13).
(2) The following dedicated instructions cannot be executed simultaneously for the
same axis.
(They can be executed simultaneously for different axes.)
• Positioning start instructions (PSTRT1 to PSTRT4)
• Absolute position restoration instructions (ABRST1 to ABRST4)
• Teaching instructions (TEACH1 to TEACH4)
(3) The PSTRT
instruction can be executed when the QD75 READY signal (X0) is
turned ON.
When the QD75 READY signal is turned OFF, the PSTRT
instruction will not be
executed even if the PSTRT
instruction execution request is given. (Not
processed.)
Before executing the PSTRT
instruction, turn ON the PLC READY signal (Y0),
and turn ON the QD75 READY signal (X0).
Program examples
The following program executes the positioning of positioning data No.100 and No.200
repeatedly when X71 turns ON.
The positioning is completed when X72 turns ON.
Use D90 to D92 as the control data devices, and M92 and M93 as the complete
devices of the positioning data No. 100.
Use D93 to D95 as the control data devices, and M95 and M96 as the complete
devices of the positioning data No. 200.
