Motion Parameters
• Operation
To repeat latch operations, set bit 4 of OW 00 to 1.
For usual latch operations, IW 44 and IW 45 are set to 0.
[ c ] Continuous Latch Operation
For continuous latch operations, bit 2 of IW 0C is set to 0. With this setting, however, the parameters IL 18,
IW 44, and IW 45 are updated when latching, so the completion of latching can be checked with those parame-
ters.
If checking the completion with bit 2 of IW
0C, reset the bit settings with the following procedures.
• The same timing is required to change the bit settings: Change bit 10 of OW 00 from 1 to 0 at the same
moment as bit 2 of IW 0C turns ON.
Precautions
When continuous latching is done for a short time, the sign of latch completion may not be detected because the update of the
communication cycle or H scan cycle is delayed.
To check if the latch was successfully completed, use IW
44 or IW 45.
If the current value is one greater than that of the previous cycle, then latching was successfully completed.
Example 1
• Condition: Latch at phase-C pulse
