Operation of the complete flags
The following describes the operation timings of the complete flags.
The user-specified complete flags are valid only when specified using FX5 operand. If dwell time is specified, the user-
specified complete flag turns on after the dwell time elapses.
FX3 compatible
Instruction execution
complete flag
(SM8029)
ON From when OPR is
condition completed to when the
drive contact is turned off
ON  OFF
When the drive contact is turned off
condition
*1 The flag turns on only for one scan when the drive contact of the instruction turns from OFF to ON.

Program example

The following is a program example of OPR operation (axis 1).
Near-point dog signal X0
(positive logic)
Zero signal X1 (positive logic)
OPR zero signal counts: 1
Count Start Time: Near-point dog

From when the following operation or
function is completed to when the drive
contact is turned off
• The axis is already used.
• Pulse output stop command
• Pulse decelerate and stop command
• All outputs disabled (SM8034)
• Write during RUN
• Deceleration stop after OPR speed
and creep speed are changed to 0
• Deceleration stop at limit detection
after the near-point dog is detected
