When executing continuous movement commands sequentially, the controller is calculating approx. 100
positions ahead. This is why the steps are displayed continuously on the PC screen or teaching-pendant
screen, regardless of the actual operation. The last step in the continuous operation section executed by
continuous movement commands will wait for the applicable operation to complete.

Do not allow the output fields to duplicate in the continuous operation section executed by continuous
movement commands.
Duplicating output fields in the continuous operation section will not achieve the expected result.
The output field will turn OFF at the start of processing of each command.
POTP

Do not let outputs 605 and 604 to duplicate, as in the
example shown at left.

Continuous operation section executed by continuous
movement commands
The final output status of duplicate 605 and 604 is indeterminable, because it is affected by the positioning
calculation time and the relationship of durations of actual operations.
