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.
