7. Configure the command source and operation mode.
a. Open the
Settings
page and set the
Command Source
to
3 - Analog
.
b. Set the
Operation Mode
to
0 - Torque Mode
.
When you have updated these settings the
Settings
page should look similar to

8. 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
