Multiplication of Count Input
Setting the count input multiplication setting to two or four times enables you to fine-tune controlling.
Figure 4.4. Example counting when count input multiplication is set
Synchronous Clear
When incremental counting in the CW (clockwise) direction is set with phase-Z positive logic, the board
clears the counter at the rising edge of the phase-A signal while the phase-Z input goes high and starts
counting at the rising edge of the phase-A signal after the phase-Z input goes low.
* When decremental counting in the CW direction is set, the board performs decremental counting at the rising edge
of the phase-A signal while the phase-B input remains low.
