Rescale the line trigger signal
The rotary encoder has its own built-in rescaler. Setting Rotary Encoder Multiply Factor to 0
produces an output frequency that is 4 times the rotary encoder output. To set the output
to be the same as rotary encoder output, set the Rotary Encoder Multiply Factor to 1 and
Rotary Encoder Drop Factor to 4.
Figure 39: Rotary Encoder Multiply Factor
The forward and reverse direction is set by changing “Rotary Encoder Direction Phase”.
Check the direction shown in the Direction Control Group to confirm the direction:
Figure 40: Rotary Encoder Direction Phase
In some situations, it is desirable to only respond to one direction, either forward or
reverse. Enable the Encoder Backlash Control function and the Scan Direction to desired
direction.
