■Description
These devices set the values to set for the current values when presets are executed.
If the preset value is set to be more than the ring length, an error occurs when the high-speed counter is started.
• The preset value can also be modified while the high-speed counter is operating. The update timing is END
processing.
• These devices also operate when the FX3 compatible high-speed counter function is valid.
■Clear timing
The timing when the device is cleared is as follows.
• Power ON, Reset, STOP→RUN

■Description
These devices set the ring length of the high-speed counters.
These set values are valid when the ring length setting is set to enabled.
• While the high-speed counter is operating, the value is not reflected even if modified. It operates in the
status when the high-speed counter starts.
• These devices do not operate when the FX3 compatible high-speed counter function is valid.
■Clear timing
The timing when the device is cleared is as follows.
• Power ON, Reset, STOP→RUN
