Configure the emulated encoder output.
a.
Expand the
Settings
tree item and open the
Encoder Emulation
page.
b.
Select
1 - Output - With once per rev index pulse
from the
Function
dropdown list.
c.
Set the
Resolution
to 2,000 lines/rev.
Note
The encoder resolution output value determines the equivalent resolution of
an incremental encoder in pulses per revolution (PPR). NI SoftMotion returns
encoder positions in encoder counts per revolution. A resolution of 2,000 lines/rev is
the same as 8,000 quadrature counts per revolution. You may want to choose a
different value depending on your application needs. In general, higher resolution
values result in more difficult servo loop tuning; lower resolution values provide less
accuracy.
