7.9.11 Positioning completion signal output waiting time (Ver.1.20 or later)

In positioning operation shorter than one scan time of the PLC, the system cannot detect "OFF" of the
positioning completion signal. As a result, the system cannot detect the status transition "from OFF to ON" of
the positioning completion signal, and cannot set to ON the next START command.
If the positioning completion signal output waiting time is set to one scan time or longer, the system can
detect the positioning completion signal in a sequence program, and can set to ON the next positioning
START command.
For positioning operation sufficiently longer than one scan time of the PLC, it is not necessary to set the
positioning completion signal output waiting time.
1. Positioning completion signal output waiting time setting
Set the time until the positioning completion flag turns ON after positioning is completed.

*1. The positioning completion signal turns ON in the following operations.
However, the positioning completion signal remains OFF even in an operation in which the positioning
completion signal usually turns ON if the position stopped by the STOP command is equivalent to the
target address position.

Setting range: 0 to 5000 ms
These bits are set (to ON) when positioning operation is normally
completed, and reset (to OFF) when the START command is set
to ON, when an error occurs, or when the error reset command is
*1
set to ON.
These bits remain OFF after positioning is stopped by the STOP
command.
• Operations in which the positioning
completion signal does not turn ON
- Mechanical zero return
- JOG operation
- Manual pulse generator
- Variable speed operation
