■Restrictions
• When using the link device, the fetch timing of the signal disperses in one link scan cycle.
• Set the movement amount per link scan so that the following formula is satisfied. If not, the actual movement amount of the
synchronous encoder and the movement amount counted by the Simple Motion module might not be matched.
Movement amount per link scan
Ex.
When using the high-speed counter module shown the setting example above, set the movement amount per link scan to
