User
*1: The data on the setting side is as follows.
• User : Data before the execution of dedicated instructions is stored by users.
• System : Data after the execution of dedicated instruction is stored by PLC CPU.
Functions
(1) The positioning start of the axes to be processed (See below) is carried out.
• PSTRT1: Axis 1
• PSTRT2: Axis 2
• 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 setting "start number" to 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 in which
PSTRT
instruction was completed, and turned OFF by the next END
processing.
(b) Complete state display device ((D)+1)
This device is turned ON or OFF according to how the PSTRT
instruction is
completed.
• When completed normally : Kept unchanged at OFF.
• When completed abnormally : This device is turned ON by the END
processing of the scan in which the PSTRT
instruction was completed, and turned OFF
by the next END processing. (Same
ON/OFF operation as the complete device).

Errors
(1) When the PSTRT
instruction is completed abnormally, the error complete signal
((D)+1) is turned ON, and the error code is stored in the complete status ((S)+1).
