Description
Can count from -1073741824 to 1073741823 and detect an
overflow when the count range is overrun.
Counts repeatedly from 0 to the "
value".
Note) When using the ring counter function, the positioning control
range is from 0 to 1073741823 (pulse).
Counts pulses while the count enable command (Y1C to Y1E) is
ON.
By presetting the " Coincidence detection point setting", this
Cd.7
function outputs ON/OFF signal as compared to the "
value".
Rewrites the " Count value" to an arbitrary value.
Md.3
Changes the " Current feed value" and the "
Md.1
value" to the same value at presetting or current value change.
Changes the external I/O signal logic to match the externally
connected device.
It can be changed by making the intelligent function module setting.
Monitors the external I/O signal status by using GX Developer.
